dm table: audit all dm_table_get_target() callers
All callers of dm_table_get_target() are expected to do proper bounds
checking on the index they pass.
Move dm_table_get_target() to dm-core.h to make it extra clear that only
DM core code should be using it. Switch it to be inlined while at it.
Standardize all DM core callers to use the same for loop pattern and
make associated variables as local as possible. Rename some variables
(e.g. s/table/t/ and s/tgt/ti/) along the way.

dm: add two stage requeue mechanism
Commit 7688da8f9848 ("dm: fix BLK_STS_DM_REQUEUE handling when dm_io
represents split bio") reverted DM core's bio splitting back to using
bio_split()+bio_chain() because it was found that otherwise DM's
BLK_STS_DM_REQUEUE would trigger a live-lock waiting for bio
completion that would never occur.
Restore using bio_trim()+bio_inc_remaining(), like was done in commit 00649850916a ("dm: improve bio splitting and associated IO
accounting"), but this time with proper handling for the above
scenario that is covered in more detail in the commit header for 7688da8f9848.
Solve this issue by adding a two staged dm_io requeue mechanism that
uses the new dm_bio_rewind() via dm_io_rewind():
1) requeue the dm_io into the requeue_list added to struct
mapped_device, and schedule it via new added requeue work. This
workqueue just clones the dm_io->orig_bio (which DM saves and
ensures its end sector isn't modified). dm_io_rewind() uses the
sectors and sectors_offset members of the dm_io that are recorded
relative to the end of orig_bio: dm_bio_rewind()+bio_trim() are
then used to make that cloned bio reflect the subset of the
original bio that is represented by the dm_io that is being
requeued.
2) the 2nd stage requeue is same with original requeue, but
io->orig_bio points to new cloned bio (which matches the requeued
dm_io as described above).
This allows DM core to shift the need for bio cloning from bio-split
time (during IO submission) to the less likely BLK_STS_DM_REQUEUE
handling (after IO completes with that error).

dm: add dm_bio_rewind() API to DM core
Commit 9e66c8ff4ff6 ("block: remove bio_rewind_iter()") removed
a similar API for the following reasons:
```
It is pointed that bio_rewind_iter() is one very bad API[1]:
1) bio size may not be restored after rewinding
2) it causes some bogus change, such as c8f3ec6dace320 (block: reset
bi_iter.bi_done after splitting bio)
3) rewinding really makes things complicated wrt. bio splitting
So this patch takes Kent's suggestion to restore one bio into its original
state via saving bio iterator(struct bvec_iter) in bio_integrity_prep(),
given now bio_rewind_iter() is only used by bio integrity code.
```
However, saving off a copy of the 32 bytes bio->bi_iter in case rewind
needed isn't efficient because it bloats per-bio-data for what is an
unlikely case. That suggestion also ignores the need to restore
crypto and integrity info.
Add dm_bio_rewind() API for a specific use-case that is much more narrow
than the previous more generic rewind code that was reverted:
1) most bios have a fixed end sector since bio split is done from front
of the bio, if driver just records how many sectors between current
bio's start sector and the original bio's end sector, the original
position can be restored. Keeping the original bio's end sector
fixed is a _hard_ requirement for this interface!
2) if a bio's end sector won't change (usually bio_trim() isn't
called, or in the case of DM it preserves original bio), user can
restore the original position by storing sector offset from the
current ->bi_iter.bi_sector to bio's end sector; together with
saving bio size, only 8 bytes is needed to restore to original
bio.
3) DM's requeue use case: when BLK_STS_DM_REQUEUE happens, DM core
needs to restore to an "original bio" which represents the current
dm_io to be requeued (which may be a subset of the original bio).
By storing the sector offset from the original bio's end sector and
dm_io's size, dm_bio_rewind() can restore such original bio. See
commit 00649850916a ("dm: improve bio splitting and associated IO
accounting") for more details on how DM does this. Leveraging this,
allows DM core to shift the need for bio cloning from bio-split
time (during IO submission) to the less likely BLK_STS_DM_REQUEUE
handling (after IO completes with that error).
4) Unlike the original rewind API, dm_bio_rewind() doesn't add .bi_done
to bvec_iter and there is no effect on the fast path.
Implement dm_bio_rewind() by factoring out clear helpers that it calls:
dm_bio_integrity_rewind, dm_bio_crypt_rewind and dm_bio_rewind_iter.
DM is able to ensure that dm_bio_rewind() is used safely but, given
the constraint that the bio's end must never change, other
hypothetical future callers may not take the same care. So make
dm_bio_rewind() and all supporting code local to DM to avoid risk of
hypothetical abuse. A "dm_" prefix was added to all functions to avoid
any namespace collisions.

block: fix default IO priority handling again
Commit 26330d5eb60a ("block: fix default IO priority handling")
introduced an inconsistency in get_current_ioprio() that tasks without
IO context return IOPRIO_DEFAULT priority while tasks with freshly
allocated IO context will return 0 (IOPRIO_CLASS_NONE/0) IO priority.
Tasks without IO context used to be rare before eaaf82e2eeab ("block:
move io_context creation into where it's needed") but after this commit
they became common because now only BFQ IO scheduler setups task's IO
context. Similar inconsistency is there for get_task_ioprio() so this
inconsistency is now exposed to userspace and userspace will see
different IO priority for tasks operating on devices with BFQ compared
to devices without BFQ. Furthemore the changes done by commit 26330d5eb60a change the behavior when no IO priority is set for BFQ IO
scheduler which is also documented in ioprio_set(2) manpage:
"If no I/O scheduler has been set for a thread, then by default the I/O
priority will follow the CPU nice value (setpriority(2)). In Linux
kernels before version 2.6.24, once an I/O priority had been set using
ioprio_set(), there was no way to reset the I/O scheduling behavior to
the default. Since Linux 2.6.24, specifying ioprio as 0 can be used to
reset to the default I/O scheduling behavior."
So make sure we default to IOPRIO_CLASS_NONE as used to be the case
before commit 26330d5eb60a. Also cleanup alloc_io_context() to
explicitely set this IO priority for the allocated IO context to avoid
future surprises. Note that we tweak ioprio_best() to maintain
ioprio_get(2) behavior and make this commit easily backportable.

When 'perf inject' creates a new file, it reuses the data offset from

happened in v5.12 -> v5.13, the new offsets will be wrong, resulting in
a corrupted output file.
This change adds the function perf_session__data_offset to compute the
data offset based on the current header size, and uses that instead of
the offset from the original input file.

Fix a boot crash on a c8000 machine as reported by Dave. Basically it changes
patch_map() to return an alias mapping to the to-be-patched code in order to
prevent writing to write-protected memory.
Anonymous pages are allocated with the shared mappings colouring,
SHM_COLOUR. Since the alias boundary on machines with PA8800 and
PA8900 processors is unknown, flush_user_cache_page() might not
flush all mappings of a shared anonymous page. Flushing the whole
data cache flushes all mappings.
This won't fix all coherency issues with shared mappings but it
seems to work well in practice. I haven't seen any random memory

LoongArch: Fix wrong fpu version
According to the configuration information accessible by the CPUCFG
instruction in LoongArch Reference Manual [1], FP_ver is stored in
bit [5: 3] of CPUCFG2, the current code to get fpu version is wrong,
use CPUCFG2_FPVERS to fix it.

LoongArch: Fix EENTRY/MERRENTRY setting in setup_tlb_handler()
setup_tlb_handler() is expected to set per-cpu exception handlers, but
it only set the TLBRENTRY successfully because of copy & paste errors,
so fix it.

LoongArch: Fix sleeping in atomic context in setup_tlb_handler()
Since setup_tlb_handler() is executed in atomic context, we should use
GFP_ATOMIC instead of GFP_KERNEL to alloc pages. Otherwise we will get
a "sleeping in atomic context" error:

_stext means the start of .text section (see __is_kernel_text()), but we
put its definition in .ref.text by mistake. Fix it by defining it in the

Fix the !THP build by making pmd_pfn() available in all configurations.
