Accessing the MCA thresholding controls in sysfs concurrently with CPU
hotplug can lead to a couple of KASAN-reported issues:
BUG: KASAN: use-after-free in sysfs_file_ops+0x155/0x180
Read of size 8 at addr ffff888367578940 by task grep/4019
and
BUG: KASAN: use-after-free in show_error_count+0x15c/0x180
Read of size 2 at addr ffff888368a05514 by task grep/4454
for example. Both result from the fact that the threshold block
creation/teardown code frees the descriptor memory itself instead of
defining proper ->release function and leaving it to the driver core to
take care of that, after all sysfs accesses have completed.
Do that and get rid of the custom freeing code, fixing the above UAFs in
the process.

This code assigns src_len (size_t) to sl (int), which causes problems
when src_len is very large. Probably nobody in the kernel should be
passing this much data to chacha20poly1305 all in one go anyway, so I
don't think we need to change the algorithm or introduce larger types
or anything. But we should at least error out early in this case and
print a warning so that we get reports if this does happen and can look
into why anybody is possibly passing it that much data or if they're
accidently passing -1 or similar.

Add Colibri SODIMM numbers as GPIO line names on module level. The GPIO
lines with a name are all available on the SODIMM edge connector of the
Colibri iMX7 module and therefore a customer might use it as a GPIO. The
Toradex Evaluation Board has the SODIMM numbers printed on the silk-
screen. This allows a customer to quickly control a GPIO on a pin-header
by using the name printed next to it.
Putting the GPIO line name on module level makes sure that a customer
gets a reasonable default. If more meaningful names are available on a
custom carrier board, the user can overwrite the line names in a carrier
board level device tree.
The eMMC based modules share all GPIO names except two GPIOs on bank 6
which are not available on the raw NAND devices. Hence overwrite GPIO
line names of bank 6 in the eMMC specific device tree file.

The difference between "fsl,etsec2-mdio" and "gianfar" has to do with
the .get_tbipa function, which calculates the address of the TBIPA
register automatically, if not explicitly specified. [ see
drivers/net/ethernet/freescale/fsl_pq_mdio.c ]. On LS1021A, the TBIPA
register is at offset 0x30 within the port register block, which is what
the "gianfar" method of calculating addresses actually does.
Luckily, the bad "compatible" is inconsequential for ls1021a.dtsi,
because the TBIPA register is explicitly specified via the second "reg"
(<0x0 0x2d10030 0x0 0x4>), so the "get_tbipa" function is dead code.
Nonetheless it's good to restore it to its correct value.

Carter reported an issue where he could produce a stall on ring exit,
when we're cleaning up requests that match the given file table. For
this particular test case, a combination of a few things caused the
issue:
- The cq ring was overflown
- The request being canceled was in the overflow list
The combination of the above means that the cq overflow list holds a
reference to the request. The request is canceled correctly, but since
the overflow list holds a reference to it, the final put won't happen.
Since the final put doesn't happen, the request remains in the inflight.
Hence we never finish the cancelation flush.
Fix this by removing requests from the overflow list if we're canceling
them.

Unlike DP 1.2 edid corruption test, DP 1.4 requires to calculate
real CRC value of the last edid data block, and write it back.
Current edid CRC calculates routine adds the last CRC byte,
and check if non-zero.
This behavior is not accurate; actually, we need to return
the actual CRC value when corruption is detected.
This commit changes this issue by returning the calculated CRC,
and initiate the required sequence.
Change since v7
- Fix for CI.CHECKPATCH
Change since v6
- Add return check
Change since v5
- Obtain real CRC value before dumping bad edid
Change since v4
- Fix for CI.CHECKPATCH
Change since v3
- Fix a minor typo.
Change since v2
- Rewrite checksum computation routine to avoid duplicated code.
- Rename to avoid confusion.

If the BIOS default timeout for the watchdog is too small userspace may
not have enough time to configure new timeout after opening the device
before the system is already reset. For this reason program default
timeout of 30 seconds in the driver probe and allow userspace to change
this from command line or through module parameter (wdat_wdt.timeout).

ACPI Generic Address Structure (GAS) access_width field is not in bytes
as the driver seems to expect in few places so fix this by using the
newly introduced macro ACPI_ACCESS_BYTE_WIDTH().

Sometimes it is useful to find the access_width field value in bytes and
not in bits so add a helper that can be used for this purpose.
