Merge branch 'from-miklos' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs updates from Al Viro: "Assorted patches from Miklos. An interesting part here is /proc/mounts stuff..." The "/proc/mounts stuff" is using a cursor for keeeping the location data while traversing the mount listing. Also probably worth noting is the addition of faccessat2(), which takes an additional set of flags to specify how the lookup is done (AT_EACCESS, AT_SYMLINK_NOFOLLOW, AT_EMPTY_PATH). * 'from-miklos' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: vfs: add faccessat2 syscall vfs: don't parse "silent" option vfs: don't parse "posixacl" option vfs: don't parse forbidden flags statx: add mount_root statx: add mount ID statx: don't clear STATX_ATIME on SB_RDONLY uapi: deprecate STATX_ALL utimensat: AT_EMPTY_PATH support vfs: split out access_override_creds() proc/mounts: add cursor aio: fix async fsync creds vfs: allow unprivileged whiteout creation |

A fair amount of stuff this time around, dominated by yet another massive
set from Mauro toward the completion of the RST conversion. I *really* hope we are getting close to the end of this. Meanwhile, those patches reach pretty far afield to update document references around the tree; there should be no actual code changes there. There will be, alas, more of the usual trivial merge conflicts. Beyond that we have more translations, improvements to the sphinx scripting, a number of additions to the sysctl documentation, and lots of fixes. -----BEGIN PGP SIGNATURE----- iQFDBAABCAAtFiEEIw+MvkEiF49krdp9F0NaE2wMflgFAl7VId8PHGNvcmJldEBs d24ubmV0AAoJEBdDWhNsDH5Yq/gH/iaDgirQZV6UZ2v9sfwQNYolNpf2sKAuOZjd bPFB7WJoMQbKwQEvYrAUL2+5zPOcLYuIfzyOfo1BV1py+EyKbACcKjI4AedxfJF7 +NchmOBhlEqmEhzx2U08HRc4/8J223WG17fJRVsV3p+opJySexSFeQucfOciX5NR RUCxweWWyg/FgyqjkyMMTtsePqZPmcT5dWTlVXISlbWzcv5NFhuJXnSrw8Sfzcmm SJMzqItv3O+CabnKQ8kMLV2PozXTMfjeWH47ZUK0Y8/8PP9+cvqwFzZ0UDQJ1Xaz oyW/TqmunaXhfMsMFeFGSwtfgwRHvXdxkQdtwNHvo1dV4dzTvDw= =fDC/ -----END PGP SIGNATURE----- Merge tag 'docs-5.8' of git://git.lwn.net/linux Pull documentation updates from Jonathan Corbet: "A fair amount of stuff this time around, dominated by yet another massive set from Mauro toward the completion of the RST conversion.

arm64 updates for 5.8
- Branch Target Identification (BTI)
* Support for ARMv8.5-BTI in both user- and kernel-space. This
allows branch targets to limit the types of branch from which
they can be called and additionally prevents branching to
arbitrary code, although kernel support requires a very recent
toolchain.
* Function annotation via SYM_FUNC_START() so that assembly
functions are wrapped with the relevant "landing pad"
instructions.
* BPF and vDSO updates to use the new instructions.
* Addition of a new HWCAP and exposure of BTI capability to
userspace via ID register emulation, along with ELF loader
support for the BTI feature in .note.gnu.property.
* Non-critical fixes to CFI unwind annotations in the sigreturn
trampoline.
- Shadow Call Stack (SCS)
* Support for Clang's Shadow Call Stack feature, which reserves
platform register x18 to point at a separate stack for each
task that holds only return addresses. This protects function
return control flow from buffer overruns on the main stack.
* Save/restore of x18 across problematic boundaries (user-mode,
hypervisor, EFI, suspend, etc).
* Core support for SCS, should other architectures want to use it
too.
* SCS overflow checking on context-switch as part of the existing
stack limit check if CONFIG_SCHED_STACK_END_CHECK=y.
- CPU feature detection
* Removed numerous "SANITY CHECK" errors when running on a system
with mismatched AArch32 support at EL1. This is primarily a
concern for KVM, which disabled support for 32-bit guests on
such a system.
* Addition of new ID registers and fields as the architecture has
been extended.
- Perf and PMU drivers
* Minor fixes and cleanups to system PMU drivers.
- Hardware errata
* Unify KVM workarounds for VHE and nVHE configurations.
* Sort vendor errata entries in Kconfig.
- Secure Monitor Call Calling Convention (SMCCC)
* Update to the latest specification from Arm (v1.2).
* Allow PSCI code to query the SMCCC version.
- Software Delegated Exception Interface (SDEI)
* Unexport a bunch of unused symbols.
* Minor fixes to handling of firmware data.
- Pointer authentication
* Add support for dumping the kernel PAC mask in vmcoreinfo so
that the stack can be unwound by tools such as kdump.
* Simplification of key initialisation during CPU bringup.
- BPF backend
* Improve immediate generation for logical and add/sub
instructions.
- vDSO
- Minor fixes to the linker flags for consistency with other
architectures and support for LLVM's unwinder.
- Clean up logic to initialise and map the vDSO into userspace.
- ACPI
- Work around for an ambiguity in the IORT specification relating
to the "num_ids" field.
- Support _DMA method for all named components rather than only
PCIe root complexes.
- Minor other IORT-related fixes.
- Miscellaneous
* Initialise debug traps early for KGDB and fix KDB cacheflushing
deadlock.
* Minor tweaks to early boot state (documentation update, set
TEXT_OFFSET to 0x0, increase alignment of PE/COFF sections).
* Refactoring and cleanup

"A sizeable pile of arm64 updates for 5.8.
Summary below, but the big two features are support for Branch Target
Identification and Clang's Shadow Call stack. The latter is currently
arm64-only, but the high-level parts are all in core code so it could
easily be adopted by other architectures pending toolchain support
Branch Target Identification (BTI):
- Support for ARMv8.5-BTI in both user- and kernel-space. This allows

Most of the changes here related to 'XSAVES supervisor state' support,
which is a feature that allows kernel-only data to be automatically saved/restored by the FPU context switching code.

Misc updates:
- Extend the x86 family/model macros with a steppings dimension,
because x86 life isn't complex enough and Intel uses steppings to
differentiate between different CPUs. :-/
- Convert the TSC deadline timer quirks to the steppings macros.
- Clean up asm mnemonics.
- Fix the handling of an AMD erratum, or in other words, fix a kernel erratum.

Kernel side changes:
- Add AMD Fam17h RAPL support
- Introduce CAP_PERFMON to kernel and user space
- Add Zhaoxin CPU support
- Misc fixes and cleanups
Tooling changes:
perf record:
- Introduce --switch-output-event to use arbitrary events to be setup
and read from a side band thread and, when they take place a signal
be sent to the main 'perf record' thread, reusing the --switch-output
code to take perf.data snapshots from the --overwrite ring buffer, e.g.:
# perf record --overwrite -e sched:* \
--switch-output-event syscalls:*connect* \
workload
will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
connect syscalls.
- Add --num-synthesize-threads option to control degree of parallelism of the
synthesize_mmap() code which is scanning /proc/PID/task/PID/maps and can be
time consuming. This mimics pre-existing behaviour in 'perf top'.
perf bench:

Pull perf updates from Ingo Molnar:
"Kernel side changes:
- Add AMD Fam17h RAPL support
- Introduce CAP_PERFMON to kernel and user space
- Add Zhaoxin CPU support
- Misc fixes and cleanups
Tooling changes:
- perf record:
Introduce '--switch-output-event' to use arbitrary events to be
setup and read from a side band thread and, when they take place a
signal be sent to the main 'perf record' thread, reusing the core
for '--switch-output' to take perf.data snapshots from the ring
buffer used for '--overwrite', e.g.:
# perf record --overwrite -e sched:* \
--switch-output-event syscalls:*connect* \
workload
will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
connect syscalls.
Add '--num-synthesize-threads' option to control degree of
parallelism of the synthesize_mmap() code which is scanning
/proc/PID/task/PID/maps and can be time consuming. This mimics
pre-existing behaviour in 'perf top'.
- perf bench:
Add a multi-threaded synthesize benchmark and kallsyms parsing
benchmark.
- Intel PT support:
Stitch LBR records from multiple samples to get deeper backtraces,
there are caveats, see the csets for details.
Allow using Intel PT to synthesize callchains for regular events.

- Updated perf vendor events for power9 and Coresight.
- Add flamegraph.py script via 'perf flamegraph'
- Misc other changes, fixes and cleanups - see the Git log for details
Also, since over the last couple of years perf tooling has matured and
decoupled from the kernel perf changes to a large degree, going
forward Arnaldo is going to send perf tooling changes via direct pull
requests"

- Speed up objtool significantly, especially when there are large number of sections
- Improve objtool's understanding of special instructions such as IRET,
to reduce the number of annotations required
- Implement 'noinstr' validation
- Do baby steps for non-x86 objtool use
- Simplify/fix retpoline decoding
- Add vmlinux validation
- Improve documentation
- Fix various bugs and apply smaller cleanups

The biggest change to core locking facilities in this cycle is the introduction
of local_lock_t - this primitive comes from the -rt project and identifies CPU-local locking dependencies normally handled opaquely beind preempt_disable() or local_irq_save/disable() critical sections. The generated code on mainline kernels doesn't change as a result, but still there are benefits: improved debugging and better documentation of data structure accesses. The new local_lock_t primitives are introduced and then utilized in a couple of kernel subsystems. No change in functionality is intended. There's also other smaller changes and cleanups.

regulator: Updates for v5.8
The big change in this release is that Matti Vaittinen has factored out
the linear ranges support into a separate library in lib/ since it is
also useful for at least the power subsystem (and most likely others
too), it helps subsystems which need to map register values into more
useful real world values do so with minimal per-driver code.
- Factoring out of the linear ranges support into a library in lib/
from Matti Vaittinen.
- Trace points for bypass mode.
- Use the consumer name in debugfs to make it easier to understand.
- New drivers for Maxim MAX77826 and MAX8998.

spi: Updates for v5.8
This has been a very active release for the DesignWare driver in
particular - after a long period of inactivity we have had a lot of
people actively working on it for unrelated reasons this cycle with some
of that work still not landed. Otherwise it's been fairly quiet for the
subsystem. Highlights include:
- Lots of performance improvements and fixes for the DesignWare driver
from Serge Semin, Andy Shevchenko, Wan Ahmad Zainie, Clement Leger,
Dinh Nguyen and Jarkko Nikula.
- Support for octal mode transfers in spidev.
- Slave mode support for the Rockchip drivers.
- Support for AMD controllers, Broadcom mspi and Raspberry Pi 4,
and Intel Elkhart Lake.

regmap: Updates for v5.8
This has been a very active release for the regmap API for some reason,
a lot of it due to new devices with odd requirements that can sensibly
be handled here.
- Add support for buses implementing a custom reg_update_bits()
method in case the bus has a native operation for this.
- Support 16 bit register addresses in SMBus.
- Allow customization of the device attached to regmap-irq.
- Helpers for bitfield operations and per-port field initializations.

block: mark bio_wouldblock_error() bio with BIO_QUIET
We really don't care about triggering buffer errors for this condition. This avoids a spew of: Buffer I/O error on dev sdc, logical block 785929, async page read Buffer I/O error on dev sdc, logical block 759095, async page read Buffer I/O error on dev sdc, logical block 766922, async page read Buffer I/O error on dev sdc, logical block 17659, async page read Buffer I/O error on dev sdc, logical block 637571, async page read Buffer I/O error on dev sdc, logical block 39241, async page read Buffer I/O error on dev sdc, logical block 397241, async page read Buffer I/O error on dev sdc, logical block 763992, async page read from -EAGAIN conditions on request allocation for async reads.

zswap: docs/vm: Fix typo accept_threshold_percent in zswap.rst
Recently, I switched over from swap-file to zramswap.
When reading the Documentation/vm/zswap.rst file I fell over this typo.
The parameter is called accept_threshold_percent not accept_threhsold_percent
in /sys/module/zswap/parameters/ directory.
Fixes:
