Originally, get_abi.pl was using spaces to separate What: parameters,
but there are several references that declare things like:
/sys/class/powercap/.../<power zone>/enabled
So, the logic was changes in order to properly address it.
That broke the second What added by
Changeset 18e49b3046 ("ABI: security: fix location for evm and ima_policy").
As the only file that defines multiple What: at the same line is
this file, let's move the second What: to a separate line.
Fixes: 18e49b3046 ("ABI: security: fix location for evm and ima_policy")

As described at Documentation/ABI/README doesn't contain an
Attribute: field.
The way sysfs ABI is supposed to work is that each different
attribute would have a separate file. So, the right way to
map this would be like:
/sys/.../dell_privacy_supported_type/mic_mute
/sys/.../dell_privacy_supported_type/camera_shutter
/sys/.../dell_privacy_current_state/mic_mute
/sys/.../dell_privacy_current_state/camera_shutter
However, it seems to late to fix that, as this was merged already on
Kernel 5.13, and a change right now would be a regression.
So, instead, let's at least fix the entry to match the expected
format.
While here, fix the format of the contact, which is not a valid
e-mail URL.
This should also fix the current warnings produced when building the
docs:
Documentation/ABI/testing/sysfs-platform-dell-privacy-wmi:35: WARNING: Unexpected indentation.
Documentation/ABI/testing/sysfs-platform-dell-privacy-wmi:2: WARNING: Unexpected indentation.

While humans may be able to understand that something like:
/sys/bus/rapidio/devices/nn:d:iiii
could actually mean:
/sys/bus/rapidio/devices/00:e:0000
This is something that computers can't easily identify. As
get_abi.pl needs to convert it into a regex, change What: lines
to:
/sys/bus/rapidio/devices/<nn>:<d>:<iiii>

All of these have been in linux-next for well over a week with no

In this cycle, we've addressed some performance issues such as lock contention,
misbehaving compress_cache, allowing extent_cache for compressed files, and new
sysfs to adjust ra_size for fadvise. In order to diagnose the performance issues
quickly, we also added an iostat which shows the IO latencies periodically. On
the stability side, we've found two memory leakage cases in the error path in
compression flow. And, we've also fixed various corner cases in fiemap, quota,
checkpoint=disable, zstd, and so on.
Enhancement:
- avoid long checkpoint latency by releasing nat_tree_lock
- collect and show iostats periodically
- support extent_cache for compressed files
- add a sysfs entry to manage ra_size given fadvise(POSIX_FADV_SEQUENTIAL)
- report f2fs GC status via sysfs
- add discard_unit=%s in mount option to handle zoned device
Bug fix:
- fix two memory leakages when an error happens in the compressed IO flow
- fix commpress_cache to get the right LBA
- fix fiemap to deal with compressed case correctly
- fix wrong EIO returns due to SBI_NEED_FSCK
- fix missing writes when enabling checkpoint back
- fix quota deadlock
- fix zstd level mount option
In addition to the above major updates, we've cleaned up several code paths such
as dio, unnecessary operations, debugfs/f2fs/status, sanity check, and typos.

Merge tag 'f2fs-for-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this cycle, we've addressed some performance issues such as lock
contention, misbehaving compress_cache, allowing extent_cache for
compressed files, and new sysfs to adjust ra_size for fadvise.
In order to diagnose the performance issues quickly, we also added an
iostat which shows the IO latencies periodically.
On the stability side, we've found two memory leakage cases in the
error path in compression flow. And, we've also fixed various corner
cases in fiemap, quota, checkpoint=disable, zstd, and so on.
Enhancements:
- avoid long checkpoint latency by releasing nat_tree_lock
- collect and show iostats periodically
- support extent_cache for compressed files
- add a sysfs entry to manage ra_size given fadvise(POSIX_FADV_SEQUENTIAL)
- report f2fs GC status via sysfs
- add discard_unit=%s in mount option to handle zoned device
Bug fixes:
- fix two memory leakages when an error happens in the compressed IO flow
- fix commpress_cache to get the right LBA
- fix fiemap to deal with compressed case correctly
- fix wrong EIO returns due to SBI_NEED_FSCK
- fix missing writes when enabling checkpoint back
- fix quota deadlock
- fix zstd level mount option
In addition to the above major updates, we've cleaned up several code
paths such as dio, unnecessary operations, debugfs/f2fs/status, sanity
check, and typos"

Some method is obviously needed to enable reclaim-based migration.
Just like traditional autonuma, there will be some workloads that will
benefit like workloads with more "static" configurations where hot pages
stay hot and cold pages stay cold. If pages come and go from the hot and
cold sets, the benefits of this approach will be more limited.
The benefits are truly workload-based and *not* hardware-based. We do not
believe that there is a viable threshold where certain hardware
configurations should have this mechanism enabled while others do not.
To be conservative, earlier work defaulted to disable reclaim- based
migration and did not include a mechanism to enable it. This proposes add
a new sysfs file
/sys/kernel/mm/numa/demotion_enabled
as a method to enable it.
We are open to any alternative that allows end users to enable this
mechanism or disable it if workload harm is detected (just like
traditional autonuma).
Once this is enabled page demotion may move data to a NUMA node that does
not fall into the cpuset of the allocating process. This could be
construed to violate the guarantees of cpusets. However, since this is an
opt-in mechanism, the assumption is that anyone enabling it is content to
relax the guarantees.

This series consists of the usual driver updates (ufs, qla2xxx,
target, smartpqi, lpfc, mpt3sas). The core change causing the most
churn was replacing the command request field request with a macro,
allowing us to offset map to it and remove the redundant field; the
same was also done for the tag field. The most impactful change is
the final removal of scsi_ioctl, which has been deprecated for over a
decade.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
- Support for 32-bit tasks on asymmetric AArch32 systems (on top of the
scheduler changes merged via the tip tree).
- More entry.S clean-ups and conversion to C.
- MTE updates: allow a preferred tag checking mode to be set per CPU
(the overhead of synchronous mode is smaller for some CPUs than
others); optimisations for kernel entry/exit path; optionally disable
MTE on the kernel command line.
- Kselftest improvements for SVE and signal handling, PtrAuth.
- Fix unlikely race where a TLBI could use stale ASID on an ASID
roll-over (found by inspection).
- Miscellaneous fixes: disable trapping of PMSNEVFR_EL1 to higher
exception levels; drop unnecessary sigdelsetmask() call in the
signal32 handling; remove BUG_ON when failing to allocate SVE state
(just signal the process); SYM_CODE annotations.
- Other trivial clean-ups: use macros instead of magic numbers, remove
redundant returns, typos.

Pull drm updates from Dave Airlie:
"Highlights:
- i915 has seen a lot of refactoring and uAPI cleanups due to a
change in the upstream direction going forward
This has all been audited with known userspace, but there may be
some pitfalls that were missed.
- i915 now uses common TTM to enable discrete memory on DG1/2 GPUs
- i915 enables Jasper and Elkhart Lake by default and has preliminary
XeHP/DG2 support
- amdgpu adds support for Cyan Skillfish
- lots of implicit fencing rules documented and fixed up in drivers
- msm now uses the core scheduler
- the irq midlayer has been removed for non-legacy drivers
- the sysfb code now works on more than x86.
Otherwise the usual smattering of stuff everywhere, panels, bridges,
refactorings.
Detailed summary:
core:
- extract i915 eDP backlight into core
- DP aux bus support

- Add a new uAPI (under the cs ioctl) to enable to user to reserve
signals and signal them from within its workloads, while the driver
performs the waiting. This allows finer granularity of pipelining
between the different engines and resource utilization.
- Add a new uAPI (under the wait_for_cs ioctl) to allow waiting
on multiple command submissions (workloads) at the same time. This
is an optimization for the user process so it won't need to call
multiple times to the wait_for_cs ioctl.
- Add new feature of "state dump", which can be triggered through new
debugfs node. This is a similar concept to the kernel panic dump.
This new mechanism retrieves information from the device in case
one of the workloads that was sent by the user got stuck. This is
very helpful for debugging the hang.
- Add a new debugfs node to perform lookup of user pointers that are
mapped to habana device's pmmu.
- Fix to the tracking of user process when running inside a container.
- Allow user to map more than 4GB of memory to the device MMU in single
IOCTL call.
- Minimize number of register reads done in GAUDI during user operation.
- Allow user to retrieve the device's server type that the device is
connected to.
- Several fixes to the code of waiting on interrupts on behalf of the
user.
- Fixes and improvements to the hint mechanism in our VA allocation.
- Update the firmware header files to the latest version while
maintaining backward compatibility with older firmware versions.
- Multiple fixes to various bugs.
