The same thing happens in two more drivers that have the same logic:

I don't think it can actually happen because the size is strictly bounded
to the available block sizes, at most 128 bytes, though inlining decisions
could lead gcc to not see that.
Use the unsafe_memcpy() helper instead of memcpy(), with the only difference
being that this skips the hardening checks that produce the warning.

There are cases when the interrupt status register (JRINTR) is non-zero,
even though:
1. An interrupt was generated, but it was masked OR
2. There was no interrupt generated at all
for the corresponding job ring.
1. The case when interrupt is masked (JRCFGR_LS[IMSK]=1b'1)
while other events have happened and are being accounted for, e.g.
-JRINTR[HALT]=2b'10 - input job ring underwent a flush of all on-going
jobs and processing of still-existing jobs (sitting in the ring) has been
halted
-JRINTR[HALT]=2b'01 - input job ring is currently undergoing a flush
-JRINTR[ENTER_FAIL]=1b'1 - SecMon / SNVS transitioned to FAIL MODE
It doesn't matter whether these events would assert the interrupt signal
or not, interrupt is anyhow masked.
2. The case when interrupt is not masked (JRCFGR_LS[IMSK]=1b'0), however
the events accounted for in JRINTR do not generate interrupts, e.g.:
-JRINTR[HALT]=2b'01
-JRINTR[ENTER_FAIL]=1b'1 and JRCFGR_MS[FAIL_MODE]=1b'0
Currently in these cases, when the JR interrupt handler is invoked (as a
consequence of JR sharing the interrupt line with other devices - e.g.
the two JRs on i.MX7ULP) it continues execution instead of returning
IRQ_NONE.
This could lead to situations like interrupt handler clearing JRINTR (and
thus also the JRINTR[HALT] field) while corresponding job ring is
suspended and then that job ring failing on resume path, due to expecting
JRINTR[HALT]=b'10 and reading instead JRINTR[HALT]=b'00.
Fix this by checking status of JRINTR[JRI] in the JR interrupt handler.
If JRINTR[JRI]=1b'0, there was no interrupt generated for this JR and
handler must return IRQ_NONE.

In caam_jr_enqueue, under heavy DDR load, smp_wmb() or dma_wmb()
fail to make the input ring be updated before the CAAM starts
reading it. So, CAAM will process, again, an old descriptor address
and will put it in the output ring. This will make caam_jr_dequeue()
to fail, since this old descriptor is not in the software ring.
To fix this, use wmb() which works on the full system instead of
inner/outer shareable domains.

In case the downstream bridge or panel uses DSI transfers before the
DSI host was actually initialized through samsung_dsim_atomic_enable()
which clears the stop state (LP11) mode, all transfers will fail.
This happens with downstream bridges that are controlled by DSI
commands such as the tc358762.
As documented in [1] DSI hosts are expected to allow transfers
outside the normal bridge enable/disable flow.
To fix this make sure that stop state is cleared in
samsung_dsim_host_transfer() which restores the previous
behavior.
We also factor out the common code to enable/disable stop state
to samsung_dsim_set_stop_state().

With that out of the way, we move on to constructing a shadow copy of

against the ondisk copy.

This series introduces simple usage and performance counters for the

xfs: stage repair information in pageable memory
In general, online repair of an indexed record set walks the filesystem
looking for records. These records are sorted and bulk-loaded into a
new btree. To make this happen without pinning gigabytes of metadata in
memory, first create an abstraction ('xfile') of memfd files so that
kernel code can access paged memory, and then an array abstraction
('xfarray') based on xfiles so that online repair can create an array of
new records without pinning memory.
These two data storage abstractions are critical for repair of space
metadata -- the memory used is pageable, which helps us avoid pinning
kernel memory and driving OOM problems; and they are byte-accessible
enough that we can use them like (very slow and programmatic) memory
buffers.
Later patchsets will build on this functionality to provide blob storage
and btrees.

xfs: fix online repair block reaping
These patches fix a few problems that I noticed in the code that deals
with old btree blocks after a successful repair.
First, I observed that it is possible for repair to incorrectly
invalidate and delete old btree blocks if they were crosslinked. The
solution here is to consult the reverse mappings for each block in the
extent -- singly owned blocks are invalidated and freed, whereas for
crosslinked blocks, we merely drop the incorrect reverse mapping.
A largeish change in this patchset is moving the reaping code to a
separate file, because the code are mostly interrelated static
functions. For now this also drops the ability to reap file blocks,
which will return when we add the bmbt repair functions.
Second, we convert the reap function to use EFIs so that we can commit
to freeing as many blocks in as few transactions as we dare. We would
like to free as many old blocks as we can in the same transaction that
commits the new structure to the ondisk filesystem to minimize the
number of blocks that leak if the system crashes before the repair fully
completes.
The third change made in this series is to avoid tripping buffer cache
assertions if we're merely scanning the buffer cache for buffers to
invalidate, and find a non-stale buffer of the wrong length. This is
primarily cosmetic, but makes my life easier.
The fourth change restructures the reaping code to try to process as many
blocks in one go as possible, to reduce logging traffic.
The last change switches the reaping mechanism to use per-AG bitmaps
defined in a previous patchset. This should reduce type confusion when
reading the source code.

This reverts commit 9c87156cce5a63735d1218f0096a65c50a7a32aa.
I have not been able to reproduce the reported -Wframe-larger-than=
warning (or disassembly) with clang-11 or clang-18.
I don't know precisely when this was fixed in llvm, but it may be time
to revert this.

Parse the device tree in early init to find the memory block size to be
used by the kernel. Consolidate the memory block size device tree parsing
to one helper and use that on both powernv and pseries. We still want to
use machine-specific callback because on all machine types other than
powernv and pseries we continue to return MIN_MEMORY_BLOCK_SIZE.
pseries_memory_block_size used to look for the second memory
block (memory@x) to determine the memory_block_size value. This patch
changed that to look at all memory blocks and make sure we can map them all
correctly using the computed memory block size value.
Add workaround to force 256MB memory block size if device driver managed
memory such as GPU memory is present. This helps to add GPU memory
that is not aligned to 1G.

In case fadump_reserve_mem() fails to reserve memory, the
reserve_dump_area_size variable will retain the reserve area size. This
will lead to /sys/kernel/fadump/mem_reserved node displaying an incorrect
memory reserved by fadump.
To fix this problem, reserve dump area size variable is set to 0 if fadump
failed to reserve memory.
Fixes: 8255da95e545 ("powerpc/fadump: release all the memory above boot memory size")
