In __tracing_open(), when max latency tracers took place on the cpu,
the time start of its buffer would be updated, then event entries with
timestamps being earlier than start of the buffer would be skipped
(see tracing_iter_reset()).
Softlockup will occur if the kernel is non-preemptible and too many
entries were skipped in the loop that reset every cpu buffer, so add
cond_resched() to avoid it.

Foxconn uses a unique firmware for their MHI based modems. So the generic
firmware from Qcom won't work. Hence, update the EDL firmware path to
include the 'foxconn' subdirectory based on the modem SoC so that the
Foxconn specific firmware could be used.
Respective firmware will be upstreamed to linux-firmware repo.

ftrace_graph_ret_addr() takes an 'idx' integer pointer that is used to
optimize the stack unwinding process. arm64 currently passes `NULL` for
this parameter which stops it from utilizing these optimizations.
Further, the current code for ftrace_graph_ret_addr() will just return
the passed in return address if it is NULL which will break this usage.
Pass a valid integer pointer to ftrace_graph_ret_addr() similar to
x86_64's stack unwinder.

We have STAT_FILL_EMPTY test case in xskxceiver that tries to process
traffic with fill queue being empty which currently fails for zero copy
ice driver after it started to use xsk_buff_can_alloc() API. That is
because xsk_queue::queue_empty_descs is currently only increased from
alloc APIs and right now if driver sees that xsk_buff_pool will be
unable to provide the requested count of buffers, it bails out early,
skipping calls to xsk_buff_alloc{_batch}().
Mentioned statistic should be handled in xsk_buff_can_alloc() from the
very beginning, so let's add this logic now. Do it by open coding
xskq_cons_has_entries() and bumping queue_empty_descs in the middle when
fill queue currently has no entries.

The members "start" and "end" of struct resource are of type
"resource_size_t" which can be 32bit wide.
Values read from OF however are always 64bit wide.
Avoid silently truncating the value and instead return an error value.
This can happen on real systems when the DT was created for a
PAE-enabled kernel and a non-PAE kernel is actually running.
For example with an arm defconfig and "qemu-system-arm -M virt".

Since commit "s390/sha3: Support sha3 performance enhancements"
the selftests of the sha3_256_s390 and sha3_512_s390 kernel digests
sometimes fail with:
alg: shash: sha3-256-s390 test failed (wrong result) on test vector 3,
cfg="import/export"
alg: self-tests for sha3-256 using sha3-256-s390 failed (rc=-22)
or with
alg: ahash: sha3-256-s390 test failed (wrong result) on test vector 3,
cfg="digest misaligned splits crossing pages"
alg: self-tests for sha3-256 using sha3-256-s390 failed (rc=-22)
The first failure is because the newly introduced context field
'first_message_part' is not copied during export and import operations.
Because of that the value of 'first_message_part' is more or less random
after an import into a newly allocated context and may or may not fit to
the state of the imported SHA3 operation, causing an invalid hash when it
does not fit.
Save the 'first_message_part' field in the currently unused field 'partial'
of struct sha3_state, even though the meaning of 'partial' is not exactly
the same as 'first_message_part'. For the caller the returned state blob
is opaque and it must only be ensured that the state can be imported later
on by the module that exported it.
The second failure is when on entry of s390_sha_update() the flag
'first_message_part' is on, and kimd is called in the first 'if (index)'
block as well as in the second 'if (len >= bsize)' block. In this case,
the 'first_message_part' is turned off after the first kimd, but the
function code incorrectly retains the NIP flag. Reset the NIP flag after
the first kimd unconditionally besides turning 'first_message_part' off.

Adding/removing large amount of pages at once to/from the CMM balloon
can result in rcu_sched stalls or workqueue lockups, because of busy
looping w/o cond_resched().
Prevent this by adding a cond_resched(). cmm_free_pages() holds a
spin_lock while looping, so it cannot be added directly to the existing
loop. Instead, introduce a wrapper function that operates on maximum 256
pages at once, and add it there.

Transparent hugepages (THP) are not supported when using the Hash Page
Table (HPT) MMU with 4K pages.
Currently a HPT-only 4K kernel still allows THP to be enabled, which
is misleading.
Add restrictions to the PPC_THP symbol so that if the kernel is
configured with 4K pages and only the HPT MMU (no Radix), then THP is
disabled.
Note that it's still possible to build a combined Radix/HPT kernel with 4K
pages, which does allow THP to be enabled at build time. As such the HPT
code still needs to provide some THP related symbols, to allow the build
to succeed, but those code paths are never run. See the stubs in
arch/powerpc/include/asm/book3s/64/hash-4k.h.

Move the Kconfig symbols related to transparent hugepages (THP) under a
separate config symbol, separate from CONFIG_PPC_BOOK3S_64.
The new symbol is automatically enabled if CONFIG_PPC_BOOK3S_64 is

the new PPC_THP symbol.

This is an adaptation of commit f3a112c0c4 ("x86,rethook,kprobes:
Replace kretprobe with rethook on x86") to powerpc.
Rethook follows the existing kretprobe implementation, but separates
it from kprobes so that it can be used by fprobe (ftrace-based
function entry/exit probes). As such, this patch also enables fprobe
to work on powerpc. The only other change compared to the existing
kretprobe implementation is doing the return address fixup in
arch_rethook_fixup_return().
Reference to other archs:
commit b57c2f1240 ("riscv: add riscv rethook implementation")
commit 7b0a096436 ("LoongArch: Replace kretprobe with rethook")
Note:
=====
In future, rethook will be only for kretprobe, and kretprobe
will be replaced by fprobe.
https://lore.kernel.org/all/172000134410.63468.13742222887213469474.stgit@devnote2/
We will adapt the above implementation for powerpc once its upstream.
Until then, we can have this implementation of rethook to serve
current kretprobe usecases.
