Dual fixes tags as two cases that were introduced in different patches.
One of those patches is a fix however and likely to have been backported
to stable kernels.
Note the second alignment marking is likely to be unnecessary, but is
left for now to keep this fix simple.

mm, arm64: Reduce ARCH_KMALLOC_MINALIGN brought to my attention that
our current IIO usage of L1CACHE_ALIGN is insufficient as their are Arm
platforms out their with non coherent DMA and larger cache lines at
at higher levels of their cache hierarchy.
Rename the define to make it's purpose more explicit. It will be used
much more widely going forwards (to replace incorrect ____cacheline_aligned
markings.
Note this patch will greatly reduce the padding on some architectures
that have smaller requirements for DMA safe buffers.
The history of changing values of ARCH_KMALLOC_MINALIGN via
ARCH_DMA_MINALIGN on arm64 is rather complex. I'm not tagging this
as fixing a particular patch from that route as it's not clear what to tag.
Most recently a change to bring them back inline was reverted because
of some Qualcomm Kryo cores with an L2 cache with 128-byte lines
sitting above the point of coherency.
c1132702c71f Revert "arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES)"
That reverts:
65688d2a05de arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES) which
refers to the change originally being motivated by Thunder x1 performance
rather than correctness.

The last resume result exposing logic in cros_ec_sleep_event()
incorrectly requires S0ix support, which doesn't work on ARM based
systems where S0ix doesn't exist. That's because cros_ec_sleep_event()
only reports the last resume result when the EC indicates the last sleep
event was an S0ix resume. On ARM systems, the last sleep event is always
S3 resume, but the EC can still detect sleep hang events in case some
other part of the AP is blocking sleep.
Always expose the last resume result if the EC supports it so that this
works on all devices regardless of S0ix support. This fixes sleep hang
detection on ARM based chromebooks like Trogdor.

For N2N + remote WWPN is bigger than local adapter, remote adapter will
login to local adapter while authentication application is not running.
When authentication application starts, the current session in FW needs to
to be invalidated.
Make sure the old session is torn down before triggering a relogin.

The driver failed to send implicit logout on session delete. For edif, this
failed to flush any lingering SA index in FW.
Set a flag to turn on implicit logout early in the session recovery to make
sure the logout will go out in case of error.

Current code prematurely sends out PRLI before authentication application
has given the OK to do so. This causes PRLI failure and session teardown.
Prevents PRLI from going out before authentication app gives the OK.

[ Upstream commit 24c796098f5395477f7f7ebf8e24f3f08a139f71 ]
The scenario is this: User loaded driver but has not started authentication
app. All sessions to secure device will exhaust all login attempts, fail,
and in stay in deleted state. Then some time later the app is started. The
driver will replenish the login retry count, trigger delete to prepare for
secure login. After deletion, relogin is triggered.
For the session that is already deleted, the delete trigger is a no-op. If
none of the sessions trigger a relogin, no progress is made.
Add a relogin trigger.

Commit e2be04c7f995 ("License cleanup: add SPDX license identifier to
uapi header files with a license") added the correct SPDX identifier to
include/uapi/linux/netfilter/xt_IDLETIMER.h.
A subsequent commit removed it for no reason and reintroduced the UAPI
license incorrectness as the file is now missing the UAPI exception
again.
Add it back and remove the GPLv2 boilerplate while at it.
