ASoC: Updates for v5.11
There's a lot of changes here but mostly cleanups and driver specific
things, the most user visible change is the support for boot time
selection of Intel DSP firmware which will make it easier for people to
move over to the preferred modern implementations in distros and other
large scale deployments.
This also includes a merge of the new auxillary bus which was done in
anticipation of use by the Intel DSP drivers which didn't quite make it.
- Lots more cleanups and simplifications from Morimoto-san.
- Support for some basic DPCM systems in the audio graph card from
Sameer Pujar.
- Remove some old pre-DT Freescale drivers for platforms that are now
DT only.
- Move selection of which Intel DSP implementation to use to boot time
rather than requiring it to be selected at build time.
- Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek RT715,
Qualcomm SM8250 and simple GPIO based muxes.

ext4: mark fc ineligible if inode gets evictied due to mem pressure
If inode gets evicted due to memory pressure, we have to remove it from the fast commit list. However, that inode may have uncommitted changes that fast commits will lose. So, just fall back to full commits in this case. Also, rename the fast commit ineligiblity reason from "EXT4_FC_REASON_MEM" to "EXT4_FC_REASON_MEM_NOMEM" for better expression.

afs: Fix afs_invalidatepage to adjust the dirty region
Fix afs_invalidatepage() to adjust the dirty region recorded in
page->private when truncating a page. If the dirty region is entirely
removed, then the private data is cleared and the page dirty state is
cleared.
Without this, if the page is truncated and then expanded again by truncate,
zeros from the expanded, but no-longer dirty region may get written back to
the server if the page gets laundered due to a conflicting 3rd-party write.
It mustn't, however, shorten the dirty region of the page if that page is
still mmapped and has been marked dirty by afs_page_mkwrite(), so a flag is
stored in page->private to record this.

afs: Wrap page->private manipulations in inline functions
The afs filesystem uses page->private to store the dirty range within a
page such that in the event of a conflicting 3rd-party write to the server,
we write back just the bits that got changed locally.
However, there are a couple of problems with this:
(1) I need a bit to note if the page might be mapped so that partial
invalidation doesn't shrink the range.
(2) There aren't necessarily sufficient bits to store the entire range of
data altered (say it's a 32-bit system with 64KiB pages or transparent
huge pages are in use).
So wrap the accesses in inline functions so that future commits can change
how this works.
Also move them out of the tracing header into the in-directory header.
There's not really any need for them to be in the tracing header.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

ext4: fast commit recovery path
This patch adds fast commit recovery path support for Ext4 file system. We add several helper functions that are similar in spirit to e2fsprogs journal recovery path handlers. Example of such functions include - a simple block allocator, idempotent block bitmap update function etc. Using these routines and the fast commit log in the fast commit area, the recovery path (ext4_fc_replay()) performs fast commit log recovery.

ext4: main fast-commit commit path
This patch adds main fast commit commit path handlers. The overall
patch can be divided into two inter-related parts:
(A) Metadata updates tracking
This part consists of helper functions to track changes that need
to be committed during a commit operation. These updates are
maintained by Ext4 in different in-memory queues. Following are
the APIs and their short description that are implemented in this
patch:
- ext4_fc_track_link/unlink/creat() - Track unlink. link and creat
operations
- ext4_fc_track_range() - Track changed logical block offsets
inodes
- ext4_fc_track_inode() - Track inodes
- ext4_fc_mark_ineligible() - Mark file system fast commit
ineligible()
- ext4_fc_start_update() / ext4_fc_stop_update() /
ext4_fc_start_ineligible() / ext4_fc_stop_ineligible() These
functions are useful for co-ordinating inode updates with
commits.
(B) Main commit Path
This part consists of functions to convert updates tracked in
in-memory data structures into on-disk commits. Function
ext4_fc_commit() is the main entry point to commit path.

Pull afs updates from David Howells:
"A collection of fixes to fix afs_cell struct refcounting, thereby
fixing a slew of related syzbot bugs:
- Fix the cell tree in the netns to use an rwsem rather than RCU.
There seem to be some problems deriving from the use of RCU and a
seqlock to walk the rbtree, but it's not entirely clear what since
there are several different failures being seen.
Changing things to use an rwsem instead makes it more robust. The
extra performance derived from using RCU isn't necessary in this
case since the only time we're looking up a cell is during mount or
when cells are being manually added.
- Fix the refcounting by splitting the usage counter into a memory
refcount and an active users counter. The usage counter was doing
double duty, keeping track of whether a cell is still in use and
keeping track of when it needs to be destroyed - but this makes the
clean up tricky. Separating these out simplifies the logic.
- Fix purging a cell that has an alias. A cell alias pins the cell
it's an alias of, but the alias is always later in the list. Trying
to purge in a single pass causes rmmod to hang in such a case.
- Fix cell removal. If a cell's manager is requeued whilst it's
removing itself, the manager will run again and re-remove itself,
causing problems in various places. Follow Hillf Danton's
suggestion to insert a more terminal state that causes the manager
to do nothing post-removal.
In additional to the above, two other changes:
- Add a tracepoint for the cell refcount and active users count. This
helped with debugging the above and may be useful again in future.
- Downgrade an assertion to a print when a still-active server is
seen during purging. This was happening as a consequence of
incomplete cell removal before the servers were cleaned up"

f2fs-for-5.10-rc1
In this round, we've added new features such as zone capacity for ZNS and a new GC policy, ATGC, along with in-memory segment management. In addition, we could improve the decompression speed significantly by changing virtual mapping method. Even though we've fixed lots of small bugs in compression support, I feel that it becomes more stable so that I could give it a try in production.

networking changes for the 5.10 merge window
Add redirect_neigh() BPF packet redirect helper, allowing to limit stack traversal in common container configs and improving TCP back-pressure. Daniel reports ~10Gbps => ~15Gbps single stream TCP performance gain. Expand netlink policy support and improve policy export to user space. (Ge)netlink core performs request validation according to declared policies. Expand the expressiveness of those policies (min/max length and bitmasks). Allow dumping policies for particular commands. This is used for feature discovery by user space (instead of kernel version parsing or trial and error). Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge. Allow more than 255 IPv4 multicast interfaces. Add support for Type of Service (ToS) reflection in SYN/SYN-ACK packets of TCPv6. In Multi-patch TCP (MPTCP) support concurrent transmission of data on multiple subflows in a load balancing scenario. Enhance advertising addresses via the RM_ADDR/ADD_ADDR options. Support SMC-Dv2 version of SMC, which enables multi-subnet deployments. Allow more calls to same peer in RxRPC. Support two new Controller Area Network (CAN) protocols - CAN-FD and ISO 15765-2:2016. Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit kernel problem. Add TC actions for implementing MPLS L2 VPNs. Improve nexthop code - e.g. handle various corner cases when nexthop objects are removed from groups better, skip unnecessary notifications and make it easier to offload nexthops into HW by converting to a blocking notifier. Support adding and consuming TCP header options by BPF programs, opening the doors for easy experimental and deployment-specific TCP option use. Reorganize TCP congestion control (CC) initialization to simplify life of TCP CC implemented in BPF. Add support for shipping BPF programs with the kernel and loading them early on boot via the User Mode Driver mechanism, hence reusing all the user space infra we have. Support sleepable BPF programs, initially targeting LSM and tracing. Add bpf_d_path() helper for returning full path for given 'struct path'. Make bpf_tail_call compatible with bpf-to-bpf calls. Allow BPF programs to call map_update_elem on sockmaps. Add BPF Type Format (BTF) support for type and enum discovery, as well as support for using BTF within the kernel itself (current use is for pretty printing structures). Support listing and getting information about bpf_links via the bpf syscall. Enhance kernel interfaces around NIC firmware update. Allow specifying overwrite mask to control if settings etc. are reset during update; report expected max time operation may take to users; support firmware activation without machine reboot incl. limits of how much impact reset may have (e.g. dropping link or not). Extend ethtool configuration interface to report IEEE-standard counters, to limit the need for per-vendor logic in user space. Adopt or extend devlink use for debug, monitoring, fw update in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx, dpaa2-eth). In mlxsw expose critical and emergency SFP module temperature alarms. Refactor port buffer handling to make the defaults more suitable and support setting these values explicitly via the DCBNL interface. Add XDP support for Intel's igb driver. Support offloading TC flower classification and filtering rules to mscc_ocelot switches. Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as fixed interval period pulse generator and one-step timestamping in dpaa-eth. Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3) offload. Add Lynx PHY/PCS MDIO module, and convert various drivers which have this HW to use it. Convert mvpp2 to split PCS. Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as 7-port Mediatek MT7531 IP. Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver, and wcn3680 support in wcn36xx. Improve performance for packets which don't require much offloads on recent Mellanox NICs by 20% by making multiple packets share a descriptor entry. Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto subtree to drivers/net. Move MDIO drivers out of the phy directory. Clean up a lot of W=1 warnings, reportedly the actively developed subsections of networking drivers should now build W=1 warning free. Make sure drivers don't use in_interrupt() to dynamically adapt their code. Convert tasklets to use new tasklet_setup API (sadly this conversion is not yet complete).

This is used for feature discovery by user space (instead of kernel version parsing or trial and error). - Support IGMPv3/MLDv2 multicast listener discovery protocols in bridge. - Allow more than 255 IPv4 multicast interfaces. - Add support for Type of Service (ToS) reflection in SYN/SYN-ACK packets of TCPv6. - In Multi-patch TCP (MPTCP) support concurrent transmission of data on multiple subflows in a load balancing scenario. Enhance advertising addresses via the RM_ADDR/ADD_ADDR options. - Support SMC-Dv2 version of SMC, which enables multi-subnet deployments. - Allow more calls to same peer in RxRPC. - Support two new Controller Area Network (CAN) protocols - CAN-FD and ISO 15765-2:2016. - Add xfrm/IPsec compat layer, solving the 32bit user space on 64bit kernel problem. - Add TC actions for implementing MPLS L2 VPNs. - Improve nexthop code - e.g. handle various corner cases when nexthop objects are removed from groups better, skip unnecessary notifications and make it easier to offload nexthops into HW by converting to a blocking notifier. - Support adding and consuming TCP header options by BPF programs, opening the doors for easy experimental and deployment-specific TCP option use. - Reorganize TCP congestion control (CC) initialization to simplify life of TCP CC implemented in BPF. - Add support for shipping BPF programs with the kernel and loading them early on boot via the User Mode Driver mechanism, hence reusing all the user space infra we have. - Support sleepable BPF programs, initially targeting LSM and tracing. - Add bpf_d_path() helper for returning full path for given 'struct path'. - Make bpf_tail_call compatible with bpf-to-bpf calls. - Allow BPF programs to call map_update_elem on sockmaps. - Add BPF Type Format (BTF) support for type and enum discovery, as well as support for using BTF within the kernel itself (current use is for pretty printing structures). - Support listing and getting information about bpf_links via the bpf syscall. - Enhance kernel interfaces around NIC firmware update. Allow specifying overwrite mask to control if settings etc. are reset during update; report expected max time operation may take to users; support firmware activation without machine reboot incl. limits of how much impact reset may have (e.g. dropping link or not). - Extend ethtool configuration interface to report IEEE-standard counters, to limit the need for per-vendor logic in user space. - Adopt or extend devlink use for debug, monitoring, fw update in many drivers (dsa loop, ice, ionic, sja1105, qed, mlxsw, mv88e6xxx, dpaa2-eth). - In mlxsw expose critical and emergency SFP module temperature alarms. Refactor port buffer handling to make the defaults more suitable and support setting these values explicitly via the DCBNL interface. - Add XDP support for Intel's igb driver. - Support offloading TC flower classification and filtering rules to mscc_ocelot switches. - Add PTP support for Marvell Octeontx2 and PP2.2 hardware, as well as fixed interval period pulse generator and one-step timestamping in dpaa-eth. - Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3) offload. - Add Lynx PHY/PCS MDIO module, and convert various drivers which have this HW to use it. Convert mvpp2 to split PCS. - Support Marvell Prestera 98DX3255 24-port switch ASICs, as well as 7-port Mediatek MT7531 IP. - Add initial support for QCA6390 and IPQ6018 in ath11k WiFi driver, and wcn3680 support in wcn36xx. - Improve performance for packets which don't require much offloads on recent Mellanox NICs by 20% by making multiple packets share a descriptor entry. - Move chelsio inline crypto drivers (for TLS and IPsec) from the crypto subtree to drivers/net. Move MDIO drivers out of the phy directory. - Clean up a lot of W=1 warnings, reportedly the actively developed subsections of networking drivers should now build W=1 warning free. - Make sure drivers don't use in_interrupt() to dynamically adapt their code. Convert tasklets to use new tasklet_setup API (sadly this conversion is not yet complete). * tag 'net-next-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (2583 commits) Revert "bpfilter: Fix build error with CONFIG_BPFILTER_UMH" net, sockmap: Don't call bpf_prog_put() on NULL pointer bpf, selftest: Fix flaky tcp_hdr_options test when adding addr to lo bpf, sockmap: Add locking annotations to iterator netfilter: nftables: allow re-computing sctp CRC-32C in 'payload' statements net: fix pos incrementment in ipv6_route_seq_next net/smc: fix invalid return code in smcd_new_buf_create() net/smc: fix valid DMBE buffer sizes net/smc: fix use-after-free of delayed events bpfilter: Fix build error with CONFIG_BPFILTER_UMH cxgb4/ch_ipsec: Replace the module name to ch_ipsec from chcr net: sched: Fix suspicious RCU usage while accessing tcf_tunnel_info bpf: Fix register equivalence tracking. rxrpc: Fix loss of final ack on shutdown rxrpc: Fix bundle counting for exclusive connections netfilter: restore NF_INET_NUMHOOKS ibmveth: Identify ingress large send packets. ibmveth: Switch order of ibmveth_helper calls. cxgb4: handle 4-tuple PEDIT to NAT mode translation selftests: Add VRF route leaking tests ... |

sound updates for 5.10
The amount of changes is smaller at this round (what a surprise),
but lots of activity is seen. Most of changes are about ASoC
driver development, especially Intel platforms.
Here are some highlights:
General:
* Replace all tasklet usages with other alternatives
* Cleanup of the ASoC error unwinding code
* Fixes for trivial issues caught by static checker
* Spell fixes allover the places
ALSA Core:
* Lockdep fix for control devices
* Fix for potential OSS sequencer mutex stalls
HD-audio and USB-audio:
* SoundBlaster AE-7 support
* Changes in quirk table for the rename handling
* Quirks for HP and ASUS machines, Pioneer DJ DJM-250MK2.
ASoC:
* Lots of updates for Intel SOF and SoundWire enablement
* Replacement of the DSP driver for some older x86 systems;
the new code was written from scratch, better maintenance
expected
* Helpers for parsing auxiluary devices from the device tree
* New support for AllWinner A64, Cirrus Logic CS4234, Mediatek
MT6359 Microchip S/PDIF TX and RX controllers, Realtek RT1015P,

Merge tag 'selinux-pr-20201012' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux updates from Paul Moore:
"A decent number of SELinux patches for v5.10, twenty two in total. The
highlights are listed below, but all of the patches pass our test
suite and merge cleanly.
- A number of changes to how the SELinux policy is loaded and managed
inside the kernel with the goal of improving the atomicity of a
SELinux policy load operation.
These changes account for the bulk of the diffstat as well as the
patch count. A special thanks to everyone who contributed patches
and fixes for this work.
- Convert the SELinux policy read-write lock to RCU.
- A tracepoint was added for audited SELinux access control events;
this should help provide a more unified backtrace across kernel and
userspace.
- Allow the removal of security.selinux xattrs when a SELinux policy
is not loaded.
- Enable policy capabilities in SELinux policies created with the
scripts/selinux/mdp tool.
- Provide some "no sooner than" dates for the SELinux checkreqprot
sysfs deprecation"

Merge tag 'for-5.10-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"Mostly core updates with a few user visible bits and fixes.
Hilights:
- fsync performance improvements
- less contention of log mutex (throughput +4%, latency -14%,
dbench with 32 clients)
- skip unnecessary commits for link and rename (throughput +6%,
latency -30%, rename latency -75%, dbench with 16 clients)
- make fast fsync wait only for writeback (throughput +10..40%,
runtime -1..-20%, dbench with 1 to 64 clients on various
file/block sizes)
- direct io is now implemented using the iomap infrastructure, that's
the main part, we still have a workaround that requires an iomap
API update, coming in 5.10
- new sysfs exports:
- information about the exclusive filesystem operation status
(balance, device add/remove/replace, ...)
- supported send stream version
Core:
- use ticket space reservations for data, fair policy using the same
infrastructure as metadata
- preparatory work to switch locking from our custom tree locks to
standard rwsem, now the locking context is propagated to all
callers, actual switch is expected to happen in the next dev cycle
- seed device structures are now using list API
- extent tracepoints print proper tree id
- unified range checks for extent buffer helpers
- send: avoid using temporary buffer for copying data
- remove unnecessary RCU protection from space infos
- remove unused readpage callback for metadata, enabling several
cleanups
- replace indirect function calls for end io hooks and remove
extent_io_ops completely
Fixes:
- more lockdep warning fixes
- fix qgroup reservation for delayed inode and an occasional
reservation leak for preallocated files
- fix device replace of a seed device
- fix metadata reservation for fallocate that leads to transaction
aborts
- reschedule if necessary when logging directory items or when
cloning lots of extents
- tree-checker: fix false alert caused by legacy btrfs root item
- send: fix rename/link conflicts for orphanized inodes
- properly initialize device stats for seed devices
- skip devices without magic signature when mounting
Other:
- error handling improvements, BUG_ONs replaced by proper handling,
fuzz fixes
- various function parameter cleanups
- various W=1 cleanups
- error/info messages improved
Mishaps:
- commit

This tree introduces static_call(), which is the idea of static_branch()
applied to indirect function calls. Remove a data load (indirection) by
modifying the text.
They give the flexibility of function pointers, but with better
performance. (This is especially important for cases where
retpolines would otherwise be used, as retpolines can be pretty
slow.)
API overview:
DECLARE_STATIC_CALL(name, func);
DEFINE_STATIC_CALL(name, func);
DEFINE_STATIC_CALL_NULL(name, typename);
static_call(name)(args...);
static_call_cond(name)(args...);
static_call_update(name, func);
x86 is supported via text patching, otherwise basic indirect calls are used,
with function pointers.
There's a second variant using inline code patching, inspired by jump-labels,
implemented on x86 as well.
The new APIs are utilized in the x86 perf code, a heavy user of function pointers,
where static calls speed up the PMU handler by 4.2% (!).
The generic implementation is not really excercised on other architectures,
outside of the trivial test_static_call_init() self-test.

Pull arm64 updates from Will Deacon:
"There's quite a lot of code here, but much of it is due to the
addition of a new PMU driver as well as some arm64-specific selftests
which is an area where we've traditionally been lagging a bit.
In terms of exciting features, this includes support for the Memory
Tagging Extension which narrowly missed 5.9, hopefully allowing
userspace to run with use-after-free detection in production on CPUs
that support it. Work is ongoing to integrate the feature with KASAN
for 5.11.
Another change that I'm excited about (assuming they get the hardware
right) is preparing the ASID allocator for sharing the CPU page-table
with the SMMU. Those changes will also come in via Joerg with the
IOMMU pull.
We do stray outside of our usual directories in a few places, mostly
due to core changes required by MTE. Although much of this has been
Acked, there were a couple of places where we unfortunately didn't get
any review feedback.
Other than that, we ran into a handful of minor conflicts in -next,
but nothing that should post any issues.
Summary:
- Userspace support for the Memory Tagging Extension introduced by
Armv8.5. Kernel support (via KASAN) is likely to follow in 5.11.

btrfs: use own btree inode io_tree owner id
Btree inode is special compared to all other inode extent io_trees, although it has a btrfs inode, it doesn't have the track_uptodate bit at all. This means a lot of things like extent locking doesn't even need to be applied to btree io tree. Since it's so special, adds a new owner value for it to make debuging a little easier.

The current trace event always output result like this: find_free_extent: root=2(EXTENT_TREE) len=16384 empty_size=0 flags=4(METADATA) find_free_extent: root=2(EXTENT_TREE) len=16384 empty_size=0 flags=4(METADATA) find_free_extent: root=2(EXTENT_TREE) len=8192 empty_size=0 flags=1(DATA) find_free_extent: root=2(EXTENT_TREE) len=8192 empty_size=0 flags=1(DATA) find_free_extent: root=2(EXTENT_TREE) len=4096 empty_size=0 flags=1(DATA) find_free_extent: root=2(EXTENT_TREE) len=4096 empty_size=0 flags=1(DATA) T's saying we're allocating data extent for EXTENT tree, which is not even possible. It's because we always use EXTENT tree as the owner for trace_find_free_extent() without using the @root from btrfs_reserve_extent(). This patch will change the parameter to use proper @root for trace_find_free_extent(): Now it looks much better: find_free_extent: root=5(FS_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP) find_free_extent: root=5(FS_TREE) len=8192 empty_size=0 flags=1(DATA) find_free_extent: root=5(FS_TREE) len=16384 empty_size=0 flags=1(DATA) find_free_extent: root=5(FS_TREE) len=4096 empty_size=0 flags=1(DATA) find_free_extent: root=5(FS_TREE) len=8192 empty_size=0 flags=1(DATA) find_free_extent: root=5(FS_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP) find_free_extent: root=7(CSUM_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP) find_free_extent: root=2(EXTENT_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP) find_free_extent: root=1(ROOT_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP) Reported-by: Hans van Kranenburg <hans@knorrie.org> CC: stable@vger.kernel.org # 5.4+ Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com> |

ASoC: Intel: Remove haswell solution
Newly added catpt solution found in sound/soc/intel/catpt is a direct replacement to sound/soc/intel/haswell. It covers all features supported by it and more - by aligning to recommended flows and requirement list based on Windows driver equivalent. No harm is done to userspace as catpt - similarly to haswell - loads no extenal topology files while sharing the exact same ADSP firmware binary. Given the above, existing haswell code is redundant so remove it.

scsi: target: core: Add CONTROL field for trace events
trace-cmd report doesn't show events from target subsystem because scsi_command_size() leaks through event format string: [target:target_sequencer_start] function scsi_command_size not defined [target:target_cmd_complete] function scsi_command_size not defined Addition of scsi_command_size() to plugin_scsi.c in trace-cmd doesn't help because an expression is used inside TP_printk(). trace-cmd event parser doesn't understand minus sign inside [ ]: Error: expected ']' but read '-' Rather than duplicating kernel code in plugin_scsi.c, provide a dedicated field for CONTROL byte.

KVM: x86: Allow deflecting unknown MSR accesses to user space
MSRs are weird. Some of them are normal control registers, such as EFER. Some however are registers that really are model specific, not very interesting to virtualization workloads, and not performance critical. Others again are really just windows into package configuration. Out of these MSRs, only the first category is necessary to implement in kernel space. Rarely accessed MSRs, MSRs that should be fine tunes against certain CPU models and MSRs that contain information on the package level are much better suited for user space to process. However, over time we have accumulated a lot of MSRs that are not the first category, but still handled by in-kernel KVM code. This patch adds a generic interface to handle WRMSR and RDMSR from user space. With this, any future MSR that is part of the latter categories can be handled in user space. Furthermore, it allows us to replace the existing "ignore_msrs" logic with something that applies per-VM rather than on the full system. That way you can run productive VMs in parallel to experimental ones where you don't care about proper MSR handling.
