parisc: Make some PDC structures accessible in uapi headers
While working on a qemu and SeaBIOS-port to parisc, those PDC structures are useful to have accessible from userspace. Signed-off-by: Helge Deller <deller@gmx.de> |

parisc: Pass endianness info to sparse
parisc is big-endian only but sparse assumes the same endianness as the building machine. This is problematic for code which expect __BYTE_ORDER__ being correctly predefined by the compiler which sparse can then pre-process differently from what gcc would. Fix this by letting sparse know about the architecture endianness.

parisc: Fix validity check of pointer size argument in new CAS implementation
As noted by Christoph Biedl, passing a pointer size of 4 in the new CAS implementation causes a kernel crash. The attached patch corrects the off by one error in the argument validity check. In reviewing the code, I noticed that we only perform word operations with the pointer size argument. The subi instruction intentionally uses a word condition on 64-bit kernels. Nullification was used instead of a cmpib instruction as the branch should never be taken. The shlw pseudo-operation generates a depw,z instruction and it clears the target before doing a shift left word deposit. Thus, we don't need to clip the upper 32 bits of this argument on 64-bit kernels. Tested with a gcc testsuite run with a 64-bit kernel. The gcc atomic code in libgcc is the only direct user of the new CAS implementation that I am aware of.

Merge branch 'nfp-flower-fixes-and-typo-in-ethtool-stats-name'
Jakub Kicinski says: ==================== nfp: flower fixes and typo in ethtool stats name This set comes from the flower offload team. From Pieter we have a fix to the semantics of the flag telling FW whether to allocate or free a mask and correction of a typo in name of one of the MAC statistics (reveive -> received, we use past participle to match HW docs). Dirk fixes propagation of max MTU to representors. John improves VXLAN offload. The old code was not using egress_dev at all, so Jiri missed it in his conversion. The validation of ingress port is still not perfect, we will have to wait for shared block dust to settle to tackle it. This is how John explains the cases: The following example rule is now correctly offloaded in net-next kernel: tc filter add dev vxlan0 ... enc_dst_port 4789 ... skip_sw \ action redirect dev nfp_p0 The following rule will not be offloaded to the NFP (previously it incorrectly matched vxlan packets - it shouldn't as ingress dev is not a vxlan netdev): tc filter add dev nfp_p0 ... enc_dst_port 4789 ... skip_sw \ action redirect dev nfp_p0 Rules that are not matching on tunnels and are an egress offload are rejected. The standard match code assumes the offloaded repr is the ingress port. Rejecting egress offloads removes the chances of false interpretation of the rules on the NFP. A know issue is that the following rule example could still be offloaded and incorrectly match tunnel data: tc filter add dev dummy ... enc_dst_port 4789 ... skip_sw \ action redirect dev nfp_p0 Because the egress register callback does not give information on the ingress netdev, the patch assumes that if it is not a repr then it is the correct tunnel netdev. This may not be the case. The chances of this happening is reduced as it is enforced that the rule match on the well known vxlan port but it is still possible. ==================== Signed-off-by: David S.

nfp: remove false positive offloads in flower vxlan
Pass information to the match offload on whether or not the repr is the
ingress or egress dev. Only accept tunnel matches if repr is the egress
dev.
This means rules such as the following are successfully offloaded:
tc .. add dev vxlan0 .. enc_dst_port 4789 .. action redirect dev nfp_p0
While rules such as the following are rejected:
tc .. add dev nfp_p0 .. enc_dst_port 4789 .. action redirect dev vxlan0
Also reject non tunnel flows that are offloaded to an egress dev.
Non tunnel matches assume that the offload dev is the ingress port and
offload a match accordingly.

nfp: fix flower offload metadata flag usage
Hardware has no notion of new or last mask id, instead it makes use of the
message type (i.e. add flow or del flow) in combination with a single bit
in metadata flags to determine when to add or delete a mask id. Previously
we made use of the new or last flags to indicate that a new mask should be
allocated or deallocated, respectively. This incorrect behaviour is fixed
by making use single bit in metadata flags to indicate mask allocation or
deallocation.

platform/x86: dell-*wmi*: Relay failed initial probe to dependent drivers
dell-wmi and dell-smbios-wmi are dependent upon dell-wmi-descriptor finishing probe successfully to probe themselves. Currently if dell-wmi-descriptor fails probing in a non-recoverable way (such as invalid header) dell-wmi and dell-smbios-wmi will continue to try to redo probing due to deferred probing. To solve this have the dependent drivers query the dell-wmi-descriptor driver whether the descriptor has been determined valid. The possible results are: -ENODEV: Descriptor GUID missing from WMI bus -EPROBE_DEFER: Descriptor not yet probed, dependent driver should wait and use deferred probing < 0: Descriptor probed, invalid. Dependent driver should return an error. 0: Successful descriptor probe, dependent driver can continue Successful descriptor probe still doesn't mean that the descriptor driver is necessarily bound at the time of initialization of dependent driver. Userspace can unbind the driver, so all methods used from driver should still be verified to return success values otherwise deferred probing be used.

because the R8A77970 driver is missing a header file that came from

We add device tree files for a couple of additional SoCs in various areas:
Allwinner R40/V40 for entertainment, Broadcom Hurricane 2 for networking,
Amlogic A113D for audio, and Renesas R-Car V3M for automotive.
As usual, lots of new boards get added based on those and other SoCs:
- Actions S500 based CubieBoard6 single-board computer
- Amlogic Meson-AXG A113D based development board
- Amlogic S912 based Khadas VIM2 single-board computer
- Amlogic S912 based Tronsmart Vega S96 set-top-box
- Allwinner H5 based NanoPi NEO Plus2 single-board computer
- Allwinner R40 based Banana Pi M2 Ultra and Berry single-board computers
- Allwinner A83T based TBS A711 Tablet
- Broadcom Hurricane 2 based Ubiquiti UniFi Switch 8
- Broadcom bcm47xx based Luxul XAP-1440/XAP-810/ABR-4500/XBR-4500
wireless access points and routers
- NXP i.MX51 based Zodiac Inflight Innovations RDU1 board
- NXP i.MX53 based GE Healthcare PPD biometric monitor
- NXP i.MX6 based Pistachio single-board computer
- NXP i.MX6 based Vining-2000 automotive diagnostic interface
- NXP i.MX6 based Ka-Ro TX6 Computer-on-Module in additional variants
- Qualcomm MSM8974 (Snapdragon 800) based Fairphone 2 phone
- Qualcomm MSM8974pro (Snapdragon 801) based Sony Xperia Z2 Tablet
- Realtek RTD1295 based set-top-boxes MeLE V9 and PROBOX2 AVA
- Renesas R-Car V3M (R8A77970) SoC and "Eagle" reference board
- Renesas H3ULCB and M3ULCB "Kingfisher" extension infotainment boards
- Renasas r8a7745 based iWave G22D-SODIMM SoM
- Rockchip rk3288 based Amarula Vyasa single-board computer
- Samsung Exynos5800 based Odroid HC1 single-board computer
For existing SoC support, there was a lot of ongoing work, as usual
most of that concentrated on the Renesas, Rockchip, OMAP, i.MX, Amlogic
and Allwinner platforms, but others were also active.
Rob Herring and many others worked on reducing the number of issues that
the latest version of 'dtc' now warns about. Unfortunately there is still
a lot left to do.
A rework of the ARM foundation model introduced several new files
for common variations of the model.

ARM: SoC platform updates for 4.15
Most of the commits are for defconfig changes, to enable newly added
drivers or features that people have started using. For the changed
lines lines, we have mostly cleanups, the affected platforms are
OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions.
The largest single change is the introduction of the TI "sysc" bus
driver, with the intention of cleaning up more legacy code.
Two new SoC platforms get added this time:
- Allwinner R40 is a modernized version of the A20 chip, now
with a Quad-Core ARM Cortex-A7. According to the manufacturer,
it is intended for "Smart Hardware"
- Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family
of chips meant for managed gigabit ethernet switches, based
around a Cortex-A9 CPU.
Finally, we gain SMP support for two platforms: Renesas R-Car E2
and Amlogic Meson8/8b, which were previously added but only supported
uniprocessor operation.

PM / runtime: Drop children check from __pm_runtime_set_status()
The check for "active" children in __pm_runtime_set_status(), when
trying to set the parent device status to "suspended", doesn't
really make sense, because in fact it is not invalid to set the
status of a device with runtime PM disabled to "suspended" in any
case. It is invalid to enable runtime PM for a device with its
status set to "suspended" while its child_count reference counter
is nonzero, but the check in __pm_runtime_set_status() doesn't
really cover that situation.
For this reason, drop the children check from __pm_runtime_set_status()
and add a check against child_count reference counters of "suspended"
devices to pm_runtime_enable().

dm bufio: fix integer overflow when limiting maximum cache size
The default max_cache_size_bytes for dm-bufio is meant to be the lesser
of 25% of the size of the vmalloc area and 2% of the size of lowmem.
However, on 32-bit systems the intermediate result in the expression
(VMALLOC_END - VMALLOC_START) * DM_BUFIO_VMALLOC_PERCENT / 100
overflows, causing the wrong result to be computed. For example, on a
32-bit system where the vmalloc area is 520093696 bytes, the result is
1174405 rather than the expected 130023424, which makes the maximum
cache size much too small (far less than 2% of lowmem). This causes
severe performance problems for dm-verity users on affected systems.
Fix this by using mult_frac() to correctly multiply by a percentage. Do
this for all places in dm-bufio that multiply by a percentage. Also
replace (VMALLOC_END - VMALLOC_START) with VMALLOC_TOTAL, which contrary
to the comment is now defined in include/linux/vmalloc.h.

dm: discard support requires all targets in a table support discards
A DM device with a mix of discard capabilities (due to some underlying devices not having discard support) _should_ just return -EOPNOTSUPP for the region of the device that doesn't support discards (even if only by way of the underlying driver formally not supporting discards). BUT, that does ask the underlying driver to handle something that it never advertised support for. In doing so we're exposing users to the potential for a underlying disk driver hanging if/when a discard is issued a the device that is incapable and never claimed to support discards. Fix this by requiring that each DM target in a DM table provide discard support as a prereq for a DM device to advertise support for discards. This may cause some configurations that were happily supporting discards (even in the face of a mix of discard support) to stop supporting discards -- but the risk of users hitting driver hangs, and forced reboots, outweighs supporting those fringe mixed discard configurations.

dm mpath: remove annoying message of 'blk_get_request() returned -11'
It is very normal to see allocation failure, especially with blk-mq request_queues, so it's unnecessary to report this error and annoy people. In practice this 'blk_get_request() returned -11' error gets logged quite frequently when a blk-mq DM multipath device sees heavy IO. This change is marked for stable@ because the annoying message in question was included in stable@ commit |

powerpc updates for 4.15
Non-highlights:
- Five fixes for the >128T address space handling, both to fix bugs in our
implementation and to bring the semantics exactly into line with x86.
Highlights:
- Support for a new OPAL call on bare metal machines which gives us a true NMI
(ie. is not masked by MSR[EE]=0) for debugging etc.
- Support for Power9 DD2 in the CXL driver.
- Improvements to machine check handling so that uncorrectable errors can be
reported into the generic memory_failure() machinery.
- Some fixes and improvements for VPHN, which is used under PowerVM to notify
the Linux partition of topology changes.
- Plumbing to enable TM (transactional memory) without suspend on some Power9
processors (PPC_FEATURE2_HTM_NO_SUSPEND).
- Support for emulating vector loads form cache-inhibited memory, on some
Power9 revisions.
- Disable the fast-endian switch "syscall" by default (behind a CONFIG), we
believe it has never had any users.
- A major rework of the API drivers use when initiating and waiting for long
running operations performed by OPAL firmware, and changes to the
powernv_flash driver to use the new API.
- Several fixes for the handling of FP/VMX/VSX while processes are using
transactional memory.
- Optimisations of TLB range flushes when using the radix MMU on Power9.
- Improvements to the VAS facility used to access coprocessors on Power9, and
related improvements to the way the NX crypto driver handles requests.
- Implementation of PMEM_API and UACCESS_FLUSHCACHE for 64-bit.

Pull user namespace update from Eric Biederman:
"The only change that is production ready this round is the work to
increase the number of uid and gid mappings a user namespace can
support from 5 to 340.
This code was carefully benchmarked and it was confirmed that in the
existing cases the performance remains the same. In the worst case
with 340 mappings an cache cold stat times go from 158ns to 248ns.
That is noticable but still quite small, and only the people who are
doing crazy things pay the cost.
This work uncovered some documentation and cleanup opportunities in
the mapping code, and patches to make those cleanups and improve the
documentation will be coming in the next merge window"

f2fs-for-4.15-rc1
In this round, we introduce sysfile-based quota support which is required
for Android by default. In addition, we allow that users are able to reserve
some blocks in runtime to mitigate performance drops in low free space.
Enhancement
- assign proper data segments according to write_hints given by user
- issue cache_flush on dirty devices only among multiple devices
- exploit cp_error flag and add more faults to enhance fault injection test
- conduct more readaheads during f2fs_readdir
- add a range for discard commands
Bug fix
- fix zero stat->st_blocks when inline_data is set
- drop crypto key and free stale memory pointer while evict_inode is failing
- fix some corner cases in free space and segment management
- fix wrong last_disk_size
This series includes lots of clean-ups and code enhancement in terms of xattr
operations, discard/flush command control. In addition, it adds versatile
debugfs entries to monitor f2fs status.

Pull f2fs updates from Jaegeuk Kim:
"In this round, we introduce sysfile-based quota support which is
required for Android by default. In addition, we allow that users are
able to reserve some blocks in runtime to mitigate performance drops
in low free space.
Enhancements:
- assign proper data segments according to write_hints given by user
- issue cache_flush on dirty devices only among multiple devices
- exploit cp_error flag and add more faults to enhance fault
injection test
- conduct more readaheads during f2fs_readdir
- add a range for discard commands
Bug fixes:
- fix zero stat->st_blocks when inline_data is set
- drop crypto key and free stale memory pointer while evict_inode is
failing
- fix some corner cases in free space and segment management
- fix wrong last_disk_size
This series includes lots of clean-ups and code enhancement in terms
of xattr operations, discard/flush command control. In addition, it
adds versatile debugfs entries to monitor f2fs status"

Merge tag 'afs-next-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull AFS updates from David Howells:
"kAFS filesystem driver overhaul.
The major points of the overhaul are:
(1) Preliminary groundwork is laid for supporting network-namespacing
of kAFS. The remainder of the namespacing work requires some way
to pass namespace information to submounts triggered by an
automount. This requires something like the mount overhaul that's
in progress.
(2) sockaddr_rxrpc is used in preference to in_addr for holding
addresses internally and add support for talking to the YFS VL
server. With this, kAFS can do everything over IPv6 as well as
IPv4 if it's talking to servers that support it.
(3) Callback handling is overhauled to be generally passive rather
than active. 'Callbacks' are promises by the server to tell us
about data and metadata changes. Callbacks are now checked when
we next touch an inode rather than actively going and looking for
it where possible.
(4) File access permit caching is overhauled to store the caching
information per-inode rather than per-directory, shared over
subordinate files. Whilst older AFS servers only allow ACLs on
directories (shared to the files in that directory), newer AFS
servers break that restriction.
To improve memory usage and to make it easier to do mass-key
removal, permit combinations are cached and shared.
(5) Cell database management is overhauled to allow lighter locks to
be used and to make cell records autonomous state machines that
look after getting their own DNS records and cleaning themselves
up, in particular preventing races in acquiring and relinquishing
the fscache token for the cell.
(6) Volume caching is overhauled. The afs_vlocation record is got rid
of to simplify things and the superblock is now keyed on the cell
and the numeric volume ID only. The volume record is tied to a
superblock and normal superblock management is used to mediate
the lifetime of the volume fscache token.
(7) File server record caching is overhauled to make server records
independent of cells and volumes. A server can be in multiple
cells (in such a case, the administrator must make sure that the
VL services for all cells correctly reflect the volumes shared
between those cells).
Server records are now indexed using the UUID of the server
rather than the address since a server can have multiple
addresses.
(8) File server rotation is overhauled to handle VMOVED, VBUSY (and
similar), VOFFLINE and VNOVOL indications and to handle rotation
both of servers and addresses of those servers. The rotation will
also wait and retry if the server says it is busy.
(9) Data writeback is overhauled. Each inode no longer stores a list
of modified sections tagged with the key that authorised it in
favour of noting the modified region of a page in page->private
and storing a list of keys that made modifications in the inode.
This simplifies things and allows other keys to be used to
actually write to the server if a key that made a modification
becomes useless.
(10) Writable mmap() is implemented. This allows a kernel to be build
entirely on AFS.
Note that Pre AFS-3.4 servers are no longer supported, though this can
be added back if necessary (AFS-3.4 was released in 1998)"

This is the bulk of pin control changes for the v4.15
kernel cycle:
Core:
- The pin control Kconfig entry PINCTRL is now turned into
a menuconfig option. This obviously has the implication of
making the subsystem menu visible in menuconfig. This is
happening because of two things:
- Intel have started to deploy and depend on pin controllers
in a way that is affecting users directly. This happens
on the highly integrated laptop chipsets named after
geographical places: baytrail, broxton, cannonlake,
cedarfork, cherryview, denverton, geminilake, lewisburg,
merrifield, sunrisepoint... It started a while back and
now it is ever more evident that this is crucial
infrastructure for x86 laptops and not an embedded
obscurity anymore. Users need to be aware.
- Pin control expanders on I2C and SPI that are
arch-agnostic. Currently Semtech SX150X and Microchip
MCP28x08 but more are expected. Users will have to be
able to configure these in directly for their set-up.
- Just go and select GPIOLIB now that we made sure that
GPIOLIB is a very vanilla subsystem. Do not depend on
it, if we need it, select it.
- Exposing the pin control subsystem in menuconfig uncovered
a bunch of obscure bugs that are now hopefully fixed,
all more or less pertaining to Blackfin.
- Unified namespace for cross-calls between pin control and
GPIO.
- New support for clock skew/delay generic DT bindings
and generic pin config options for this.
- Minor documentation improvements.
Various:
- The Renesas SH-PFC pin controller has evolved a lot. It seems
Renesas are churning out new SoCs by the minute.
- A bunch of non-critical fixes for the Rockchip driver.
- Improve the use of library functions instead of open coding.
- Support the MCP28018 variant in the MCP28x08 driver.
- Static constifying.

Driver core patches for 4.15-rc1
Here is the set of driver core / debugfs patches for 4.15-rc1. Not many here, mostly all are debugfs fixes to resolve some long-reported problems with files going away with references to them in userspace. There's also some SPDX cleanups for the debugfs code, as well as a few other minor driver core changes for issues reported by people. All of these have been in linux-next for a week or more with no reported issues.

kbuild: move coccicheck help from scripts/Makefile.help to top Makefile
In my view, it is not helpful to have a separate file just for the coccicheck help message. Merge scripts/Makefile.help into the top-level Makefile. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> |

zfcp: purely mechanical update using timer API, plus blank lines
erp_memwait only occurs in seldom memory pressure situations. The typical case never uses the associated timer and thus also does not need to initialize the timer. Also, we don't want to re-initialize the timer each time we re-use an erp_action in zfcp_erp_setup_act() [see also v4.14-rc7 commit |

s390/scsi: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

s390/cpum_sf: correctly set the PID and TID in perf samples
The hardware sampler creates samples that are processed at a later point in time. The PID and TID values of the perf samples that are created for hardware samples are initialized with values from the current task. Hence, the PID and TID values are not correct and perf samples are associated with wrong processes. The PID and TID values are obtained from the Host Program Parameter (HPP) field in the basic-sampling data entries. These PIDs are valid in the init PID namespace. Ensure that the PIDs in the perf samples are resolved considering the PID namespace in which the perf event was created. To correct the PID and TID values in the created perf samples, a special overflow handler is installed. It replaces the default overflow handler and does not become effective if any other overflow handler is used. With the special overflow handler most of the perf samples are associated with the right processes. For processes, that are no longer exist, the association might still be wrong.

s390/cpum_sf: load program parameter at sampler enablement
The lpp instruction is used to place the PID of the current task in the program-parameter (PP) register. The register contents is then included in the sampling data entries. The lpp instruction loads the PP register only when at least one sampling function is enabled. Otherwise it is executed as a no-op. Linux calls lpp at context switch. If the context switch happens before the sampler is enabled, the PP register is empty. That means, the PID of the task that is sampled is not stored in sampling data until the next context switch. Hence, always call lpp when enabling the sampler. Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> |
