In function pci1xxxx_spi_probe, there is a potential null pointer that
may be caused by a failed memory allocation by the function devm_kzalloc.
Hence, a null pointer check needs to be added to prevent null pointer
dereferencing later in the code.
To fix this issue, spi_bus->spi_int[iter] should be checked. The memory
allocated by devm_kzalloc will be automatically released, so just directly
return -ENOMEM without worrying about memory leaks.

When we're engaged in local caching of a cifs filesystem, we cannot perform
caching of a partially written cache granule unless we can read the rest of
the granule. This can result in unexpected access errors being reported to
the user.
Fix this by the following: if a file is opened O_WRONLY locally, but the
mount was given the "-o fsc" flag, try first opening the remote file with
GENERIC_READ|GENERIC_WRITE and if that returns -EACCES, try dropping the
GENERIC_READ and doing the open again. If that last succeeds, invalidate
the cache for that file as for O_DIRECT.

As already anticipated in the original commit, playback was broken for
very short samples. I just didn't expect it to be an actual problem,
because we're talking about less than 1.5 milliseconds here. But clearly
such wavetable samples do actually exist.
The problem was that for such short samples we'd set the current
position beyond the end of the loop, so we'd run off the end of the
sample and play garbage.
This is a bigger (more audible) problem than the original one, which was
that we'd start playback with garbage (whatever was still in the cache),
which would be mostly masked by the note's attack phase.
So revert to the old behavior for now. We'll subsequently fix it
properly with a bigger patch series.
Note that this isn't a full revert - the dead code is not re-introduced,
because that would be silly.

The myrb and myrs drivers use an odd way of implementing their sysfs files,
calling snprintf() with a fixed length of 32 bytes to print into a page
sized buffer. One of the strings is actually longer than 32 bytes, which
clang can warn about:
drivers/scsi/myrb.c:1906:10: error: 'snprintf' will always be truncated; specified size is 32, but format string expands to at least 34 [-Werror,-Wformat-truncation]
drivers/scsi/myrs.c:1089:10: error: 'snprintf' will always be truncated; specified size is 32, but format string expands to at least 34 [-Werror,-Wformat-truncation]
These could all be plain sprintf() without a length as the buffer is always
long enough. On the other hand, sysfs files should not be overly long
either, so just double the length to make sure the longest strings don't
get truncated here.

[ Upstream commit d6911cf27e5c8491cbfedd4ae2d1ee74a3e685b4 ]
The driver is wrong because is using partial register field masks for the
SPI_STATUS.{RX, TX}_FIFO_LVL register fields.
We see s3c64xx_spi_port_config.fifo_lvl_mask with different values for
different instances of the same IP. Take s5pv210_spi_port_config for
example, it defines:
.fifo_lvl_mask = { 0x1ff, 0x7F },
fifo_lvl_mask is used to determine the FIFO depth of the instance of the
IP. In this case, the integrator uses a 256 bytes FIFO for the first SPI
instance of the IP, and a 64 bytes FIFO for the second instance. While
the first mask reflects the SPI_STATUS.{RX, TX}_FIFO_LVL register
fields, the second one is two bits short. Using partial field masks is
misleading and can hide problems of the driver's logic.
Allow platforms to specify the full FIFO mask, regardless of the FIFO
depth.
Introduce {rx, tx}_fifomask to represent the SPI_STATUS.{RX, TX}_FIFO_LVL
register fields. It's a shifted mask defining the field's length and
position. We'll be able to deprecate the use of @rx_lvl_offset, as the
shift value can be determined from the mask. The existing compatibles
shall start using {rx, tx}_fifomask so that they use the full field mask
and to avoid shifting the mask to position, and then shifting it back to
zero in the {TX, RX}_FIFO_LVL macros.
@rx_lvl_offset will be deprecated in a further patch, after we have the
infrastructure to deprecate @fifo_lvl_mask as well.
No functional change intended.

In snd_soc_info_volsw(), mask is generated by figuring out the index of
the most significant bit set in max and converting the index to a
bitmask through bit shift 1. Unintended wraparound occurs when max is an
integer value with msb bit set. Since the bit shift value 1 is treated
as an integer type, the left shift operation will wraparound and set
mask to 0 instead of all 1's. In order to fix this, we type cast 1 as
`1ULL` to prevent the wraparound.

[ Upstream commit 00bb549d7d63a21532e76e4a334d7807a54d9f31 ]
When keeping the upper end of a cache block entry, the entry[] array
must be indexed by the offset from the base register of the block,
i.e. max - mas.index.
The code was indexing entry[] by only the register address, leading
to an out-of-bounds access that copied some part of the kernel
memory over the cache contents.
This bug was not detected by the regmap KUnit test because it only
tests with a block of registers starting at 0, so mas.index == 0.

When you try to splice between a normal pipe and a notification pipe,
get_pipe_info(..., true) fails, so splice() falls back to treating the
notification pipe like a normal pipe - so we end up in
iter_file_splice_write(), which first locks the input pipe, then calls
vfs_iter_write(), which locks the output pipe.
Lockdep complains about that, because we're taking a pipe lock while
already holding another pipe lock.
I think this probably (?) can't actually lead to deadlocks, since you'd
need another way to nest locking a normal pipe into locking a
watch_queue pipe, but the lockdep annotations don't make that clear.
Bail out earlier in pipe_write() for notification pipes, before taking
the pipe lock.

Convert all local ASID variables and parameters throughout the SEV code
from signed integers to unsigned integers. As ASIDs are fundamentally
unsigned values, and the global min/max variables are appropriately
unsigned integers, too.
Functionally, this is a glorified nop as KVM guarantees min_sev_asid is
non-zero, and no CPU supports -1u as the _only_ asid, i.e. the signed vs.
unsigned goof won't cause problems in practice.
Opportunistically use sev_get_asid() in sev_flush_encrypted_page() instead
of open coding an equivalent.

ravb_poll() initial code used to interrogate the first descriptor of the
RX queue in case gPTP is false to determine if ravb_rx() should be called.
This is done for non-gPTP IPs. For gPTP IPs the driver PTP-specific
information was used to determine if receive function should be called. As
every IP has its own receive function that interrogates the RX descriptors
list in the same way the ravb_poll() was doing there is no need to double
check this in ravb_poll(). Removing the code from ravb_poll() leads to a
cleaner code.

On some Meteor Lake systems accessing the PHY via the MDIO interface may

access attempts fail. The retry mechanism is disabled in specific flows,
where MDI errors are expected.

dependencies in i40e driver:
i40e.h -> i40e_virtchnl_pf.h -> i40e.h

dependencies on other header files (both private and standard) so their
inclusion in .c file require to add these deps in certain order to
that .c file to make it compilable.
Fix both issues by removal the mentioned circular dependency, by filling
