All internal use cases for tracepoint_probe_register() is set to not ever
be called with the same function and data. If it is, it is considered a
bug, as that means the accounting of handling tracepoints is corrupted.
If the function and data for a tracepoint is already registered when
tracepoint_probe_register() is called, it will call WARN_ON_ONCE() and
return with EEXISTS.
The BPF system call can end up calling tracepoint_probe_register() with
the same data, which now means that this can trigger the warning because
of a user space process. As WARN_ON_ONCE() should not be called because
user space called a system call with bad data, there needs to be a way to
register a tracepoint without triggering a warning.
Enter tracepoint_probe_register_may_exist(), which can be called, but will
not cause a WARN_ON() if the probe already exists. It will still error out
with EEXIST, which will then be sent to the user space that performed the
BPF system call.
This keeps the previous testing for issues with other users of the
tracepoint code, while letting BPF call it with duplicated data and not
warn about it.

MT8195 mmc host IP is compatible with MT8183, and currently it shows:

compatible:
oneOf:
...
- items:
- const: mediatek,mt8192-mmc
- const: mediatek,mt8195-mmc
- const: mediatek,mt8183-mmc
which means the compatible string in the device tree would be:
compatible = "mediatek,mt8192-mmc", "mediatek,mt8195-mmc",
"mediatek,mt8183-mmc";
The bindings is wrong and that isn't the result we want.

When DMA-mapping of the bounce buffer fails, the driver tries to fall
back, but it leaves the allocated host->bounce_buffer although its
size is zero. Later on, the driver checks the use of bounce buffer
with host->bounce_buffer pointer, and it tries to use the buffer
incorrectly, resulting in Oops.
This patch clears the release the unused buffer and clears the
bounce_buffer pointer for addressing the problem.

Since the EMMC clock was changed from 200Mhz to 175Mhz in FIP,
there were some warnings introduced, as the frequency values
being checked was still wrt 200Mhz in code. Hence, the frequency
checks are now updated based on the current 175Mhz EMMC clock changed
in FIP.

It might be that something goes wrong during tuning so the MMC core will
immediately trigger a retune. In our case it was:
- we sent a tuning block
- there was an error so we need to send an abort cmd to the eMMC
- the abort cmd had a CRC error
- retune was set by the MMC core
This lead to a vicious circle causing a performance regression of 75%.
So, clear retuning flags before we enable retuning to start with a known
cleared state.

ll_new_hw_segment() is reached only in case of single range discard
merge, and we don't have max discard segment size limit actually, so
it is wrong to run the following check:
if (req->nr_phys_segments + nr_phys_segs > blk_rq_get_max_segments(req))
it may be always false since req->nr_phys_segments is initialized as
one, and bio's segment count is still 1, blk_rq_get_max_segments(reg)
is 1 too.
Fix the issue by not doing the check and bypassing the calculation of
discard request's nr_phys_segments.

The cause of the problem is as follows:
1. when cat /sys/devices/system/memory/memory0/valid_zones,
test_pages_in_a_zone() will be called.
2. test_pages_in_a_zone() finds the zone according to stat_pfn = 0.
The smallest pfn of the numa node in the mips architecture is 128,
and the page corresponding to the previous 0~127 pfn is not
initialized (page->flags is 0xFFFFFFFF)
3. The nid and zonenum obtained using page_zone(pfn_to_page(0)) are out
of bounds in the corresponding array,
&NODE_DATA(page_to_nid(page))->node_zones[page_zonenum(page)],
access to the out-of-bounds zone member variables appear abnormal,
resulting in Oops.
Therefore, it is necessary to keep the page between 0 and the minimum
pfn to prevent Oops from appearing.

Currently firmware passes CCF specific flags to ZynqMP clock driver.
So firmware needs to be updated if CCF flags are changed. The firmware
should have its own 'flag number space' that is distinct from the
common clk framework's 'flag number space'. So define and use ZynqMP
specific common clock flags instead of using CCF flags.

"Use normal block device I/O path for pstore/blk. (Christoph Hellwig,
Kees Cook, Pu Lehui)"
* tag 'pstore-v5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
pstore/blk: Include zone in pstore_device_info
pstore/blk: Fix kerndoc and redundancy on blkdev param
pstore/blk: Use the normal block device I/O path
pstore/blk: Move verify_size() macro out of function
pstore/blk: Improve failure reporting
- Some kernel-doc cleanups. That script is still regex onslaught from
hell, but it has gotten a little better.
- Improvements to the checkpatch docs, which are also used by the tool
itself.
- A major update to the pathname lookup documentation.
- Elimination of :doc: markup, since our automarkup magic can create
references from filenames without all the extra noise.
- The flurry of Chinese translation activity continues.
Plus, of course, the usual collection of updates, typo fixes, and warning
fixes.

Pull btrfs updates from David Sterba:
"A normal mix of improvements, core changes and features that user have
been missing or complaining about.
User visible changes:
- new sysfs exports:
- add sysfs knob to limit scrub IO bandwidth per device
- device stats are also available in
/sys/fs/btrfs/FSID/devinfo/DEVID/error_stats
- support cancellable resize and device delete ioctls
- change how the empty value is interpreted when setting a property,
so far we have only 'btrfs.compression' and we need to distinguish
a reset to defaults and setting "do not compress", in general the
empty value will always mean 'reset to defaults' for any other
property, for compression it's either 'no' or 'none' to forbid
compression
Performance improvements:
- no need for full sync when truncation does not touch extents,
reported run time change is -12%
- avoid unnecessary logging of xattrs during fast fsyncs (+17%
throughput, -17% runtime on xattr stress workload)
Core:
- preemptive flushing improvements and fixes
- adjust clamping logic on multi-threaded workloads to avoid
flushing too soon
- take into account global block reserve, may help on almost full
filesystems
- continue flushing when there are enough pending delalloc and
ordered bytes
- simplify logic around conditional transaction commit, a workaround
used in the past for throttling that's been superseded by ticket
reservations that manage the throttling in a better way
- subpage blocksize preparation:
- submit read time repair only for each corrupted sector
- scrub repair now works with sectors and not pages
- free space cache (v1) works with sectors and not pages
- more fine grained bio tracking for extents
- subpage support in page callbacks, extent callbacks, end io
callbacks
- simplify transaction abort logic and always abort and don't check
various potentially unreliable stats tracked by the transaction
- exclusive operations can do more checks when started and allow eg.
cancellation of the same running operation
- ensure relocation never runs while we have send operations running,
e.g. when zoned background auto reclaim starts
Fixes:
- zoned: more sanity checks of write pointer
- improve error handling in delayed inodes
- send:
- fix invalid path for unlink operations after parent
orphanization
- fix crash when memory allocations trigger reclaim
- skip compression of we have only one page (can't make things
better)
- empty value of a property newly means reset to default
Other:
- lots of cleanups, comment updates, yearly typo fixing
- disable build on platforms having page size 256K"
