HMM patches for 5.3
Improvements and bug fixes for the hmm interface in the kernel:
- Improve clarity, locking and APIs related to the 'hmm mirror' feature
merged last cycle. In linux-next we now see AMDGPU and nouveau to be
using this API.
- Remove old or transitional hmm APIs. These are hold overs from the past
with no users, or APIs that existed only to manage cross tree conflicts.
There are still a few more of these cleanups that didn't make the merge
window cut off.
- Improve some core mm APIs:
* export alloc_pages_vma() for driver use
* refactor into devm_request_free_mem_region() to manage
DEVICE_PRIVATE resource reservations
* refactor duplicative driver code into the core dev_pagemap
struct
- Remove hmm wrappers of improved core mm APIs, instead have drivers use
the simplified API directly
- Remove DEVICE_PUBLIC
- Simplify the kconfig flow for the hmm users and core code

stream_open related bits for Linux 5.3

platform-drivers-x86 for v5.3-1
ASUS WMI driver got a big refactoring in order to support the TUF Gaming laptops. Besides that, the regression with backlight being permanently off on various EeePC laptops has been fixed. Accelerometer on HP ProBook 450 G0 shows wrong measurements due to X axis being inverted. This has been fixed. Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. From now on the Intel Speed Select Technology is supported thru a corresponding driver. This driver provides an access to the features of the ISST, such as Performance Profile, Core Power, Base frequency and Turbo Frequency. Mellanox platform drivers has been refactored and now extended to support more systems, including new coming ones. The OLPC XO-1.75 platform is now supported. CB4063 Beckhoff Automation board is using PMC clocks, provided via pmc_atom driver, for ethernet controllers in a way that they can't be managed by the clock driver. The quirk has been extended to cover this case. Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile the information of Chuwi Hi10 Air has been fixed to cover more models based on the same platform. Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it has been provided. It required some extension of the generic WMI library, which allows to propagate opaque context to the ->probe() of the individual drivers. This release includes debugfs clean up from Greg KH for several drivers that drop return code check and make debugfs absence or failure non-fatal. Miscellaneous fixes here and there, mostly for Acer WMI and various Intel drivers. The listed below commits are duplicated due to previously pushed fixes in v5.2 cycle: - |

powerpc updates for 5.3
Notable changes:
- Removal of the NPU DMA code, used by the out-of-tree Nvidia driver, as well
as some other functions only used by drivers that haven't (yet?) made it
upstream.
- A fix for a bug in our handling of hardware watchpoints (eg. perf record -e
mem: ...) which could lead to register corruption and kernel crashes.
- Enable HAVE_ARCH_HUGE_VMAP, which allows us to use large pages for vmalloc
when using the Radix MMU.
- A large but incremental rewrite of our exception handling code to use gas
macros rather than multiple levels of nested CPP macros.
And the usual small fixes, cleanups and improvements.

This is the bulk of pin control changes for the v5.3 kernel
cycle:
Core changes:
- Device links can optionally be added between a pin control
producer and its consumers. This will affect how the system
power management is handled: a pin controller will not suspend
before all of its consumers have been suspended. This was
necessary for the ST Microelectronics STMFX expander and
need to be tested on other systems as well: it makes sense
to make this default in the long run. Right now it is
opt-in per driver.
- Drive strength can be specified in microamps. With decreases
in silicon technology, milliamps isn't granular enough, let's
make it possible to select drive strengths in microamps. Right
now the Meson (AMlogic) driver needs this.
New drivers:
- New subdriver for the Tegra 194 SoC.
- New subdriver for the Qualcomm SDM845.
- New subdriver for the Qualcomm SM8150.
- New subdriver for the Freescale i.MX8MN (Freescale is now a
product line of NXP).
- New subdriver for Marvell MV98DX1135.
Driver improvements:
- The Bitmain BM1880 driver now supports pin config in
addition to muxing.
- The Qualcomm drivers can now reserve some GPIOs as taken
aside and not usable for users. This is used in ACPI systems
to take out some GPIO lines used by the BIOS so that
noone else (neither kernel nor userspace) will play with them
by mistake and crash the machine.
- A slew of refurbishing around the Aspeed drivers (board
management controllers for servers) in preparation for the
new Aspeed AST2600 SoC.
- A slew of improvements over the SH PFC drivers as usual.
- Misc cleanups and fixes.

Pull io_uring updates from Jens Axboe:
"This contains:
- Support for recvmsg/sendmsg as first class opcodes.
I don't envision going much further down this path, as there are
plans in progress to support potentially any system call in an
async fashion through io_uring. But I think it does make sense to
have certain core ops available directly, especially those that can
support a "try this non-blocking" flag/mode. (me)
- Handle generic short reads automatically.
This can happen fairly easily if parts of the buffered read is
cached. Since the application needs to issue another request for
the remainder, just do this internally and save kernel/user
roundtrip while providing a nicer more robust API. (me)

locking/lockdep: Fix lock used or unused stats error
The stats variable nr_unused_locks is incremented every time a new lock class is register and decremented when the lock is first used in __lock_acquire(). And after all, it is shown and checked in lockdep_stats. However, under configurations that either CONFIG_TRACE_IRQFLAGS or CONFIG_PROVE_LOCKING is not defined: The commit: |

perf/x86/intel: Fix spurious NMI on fixed counter
If a user first sample a PEBS event on a fixed counter, then sample a non-PEBS event on the same fixed counter on Icelake, it will trigger spurious NMI. For example: perf record -e 'cycles:p' -a perf record -e 'cycles' -a The error message for spurious NMI: [June 21 15:38] Uhhuh. NMI received for unknown reason 30 on CPU 2. [ +0.000000] Do you have a strange power saving mode enabled? [ +0.000000] Dazed and confused, but trying to continue The bug was introduced by the following commit: commit |

perf/core: Fix exclusive events' grouping
So far, we tried to disallow grouping exclusive events for the fear of
complications they would cause with moving between contexts. Specifically,
moving a software group to a hardware context would violate the exclusivity
rules if both groups contain matching exclusive events.
This attempt was, however, unsuccessful: the check that we have in the
perf_event_open() syscall is both wrong (looks at wrong PMU) and
insufficient (group leader may still be exclusive), as can be illustrated
by running:
$ perf record -e '{intel_pt//,cycles}' uname
$ perf record -e '{cycles,intel_pt//}' uname
ultimately successfully.
Furthermore, we are completely free to trigger the exclusivity violation
by:
perf -e '{cycles,intel_pt//}' -e '{intel_pt//,instructions}'
even though the helpful perf record will not allow that, the ABI will.
The warning later in the perf_event_open() path will also not trigger, because
it's also wrong.
Fix all this by validating the original group before moving, getting rid
of broken safeguards and placing a useful one to perf_install_in_context().

f2fs-for-5.3-rc1
In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads. In addition, we've fixed subtle quota corruption issue. Enhancement: - add swap file support which uses DIO - allocate blocks for pinned file - allow SSR and mount option to enhance checkpoint=disable - enhance IPU IOs - add more sanity checks such as memory boundary access Bug fix: - quota corruption in very corner case of error-injected SPO case - fix root_reserved on remount and some wrong counts - add missing fsck flag Some patches were also introduced to clean up ambiguous i_flags and debugging messages codes. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl0mlKIACgkQQBSofoJI UNI2Ow//e4QxinKVdgA6F2wx0CkdSreqfzQbA1t+6pcWgzCgLfj4dpOuSp8Yu1NT aG6YFfUxjtUNN8D85WqJ+6qKt0gFBoxjQXDvvbxLFB9Xoa2XqzFrHW8xenSRHppj V63Yye5Z+Qgss65hTktgHMWSi4mUWRq76t1lFBprXm41uC036rIQCSYioztcLQCN fFi2xfkFHf7vIIg6ZrCy22wNSCWL9X6dzKftIZ6LSz+jkPGEard1D/OUYLMMQ4YG b5DS0LEWbudn1vwALPPXwTHgZuG12W581MsHUsu2FIyenGGTk7EIZfNBN6cGfIMk NsEMnanFvXp7ZYP6HQnZlSkoBRIkD2JpYh7bFxTklw4H09GJxYFksed8uqNoDRog GPcNZjKSm0wCUHe2awOhF9kRXMFnwIR7m4DNOQHH1MYmpp3ponGsbfYy3J/qLS5y Smh8pcbsttDMQ0NaWZznby2bSEv9k9R9CoqE5sKCNDnh6Ky8WjK8x6xt3wrPG6h8 jI7venvHvJbFpxAmnKDzflZrlGj95pg0j0DAk07ql/9i8YPfRrlBKv8jOo+7aRWC jIO70URGDO6R/o5XdRqx6u8DOE1JPVP+6XzsT6MdDtBlxE+TbcTPRt3RzEgmo1d3 CI0jq0IRDTDZJITmQoQKCS85OZDyaAe2iHUPwSjCEuDex5lynuY= =S2ZS -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads.

- Add a multithreaded iwalk implementation to speed up quotacheck on
fast storage with many CPUs.
- Remove unnecessary return values in logging teardown functions.
- Supplement the bstat and inogrp structures with new bulkstat and
inumbers structures that have all the fields we need for v5
filesystem features and none of the padding problems of their
predecessors.
- Wire up new ioctls that use the new structures with a much simpler
bulk_ireq structure at the head instead of the pointerhappy mess we
had before.
- Enable userspace to constrain bulkstat returns to a single AG or a
single special inode so that we can phase out a lot of geometry
guesswork in userspace.
- Reduce memory consumption and zeroing overhead in extended attribute
scrub code.
- Fix some behavioral regressions in the new bulkstat backend code.
- Fix some behavioral regressions in the new log bio code.

Pull common SETFLAGS/FSSETXATTR parameter checking from Darrick Wong:
"Here's a patch series that sets up common parameter checking functions
for the FS_IOC_SETFLAGS and FS_IOC_FSSETXATTR ioctl implementations.
The goal here is to reduce the amount of behaviorial variance between
the filesystems where those ioctls originated (ext2 and XFS,
respectively) and everybody else.
- Standardize parameter checking for the SETFLAGS and FSSETXATTR
ioctls (which were the file attribute setters for ext4 and xfs and
have now been hoisted to the vfs)
- Only allow the DAX flag to be set on files and directories"
* tag 'vfs-fix-ioctl-checking-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
vfs: only allow FSSETXATTR to set DAX flag on files and dirs
vfs: teach vfs_ioc_fssetxattr_check to check extent size hints

cxgb4: reduce kernel stack usage in cudbg_collect_mem_region()
The cudbg_collect_mem_region() and cudbg_read_fw_mem() both use several
hundred kilobytes of kernel stack space. One gets inlined into the other,
which causes the stack usage to be combined beyond the warning limit
when building with clang:
drivers/net/ethernet/chelsio/cxgb4/cudbg_lib.c:1057:12: error: stack frame size of 1244 bytes in function 'cudbg_collect_mem_region' [-Werror,-Wframe-larger-than=]
Restructuring cudbg_collect_mem_region() lets clang do the same
optimization that gcc does and reuse the stack slots as it can
see that the large variables are never used together.
A better fix might be to avoid using cudbg_meminfo on the stack
altogether, but that requires a larger rewrite.
Fixes:

tipc_named_node_up() creates a skb list. It passes the list to tipc_node_xmit() which has some code paths that can call skb_queue_purge() which relies on the list->lock being initialised. The spin_lock is only needed if the messages end up on the receive path but when the list is created in tipc_named_node_up() we don't necessarily know if it is going to end up there. Once all the skb list users are updated in tipc it will then be possible to update them to use the unlocked variants of the skb list functions and initialise the lock when we know the message will follow the receive path.
