dispnv50 references the crtc->state pointer in order to get the current
CRTC state in its atomic_check hook, which would be the old CRTC state in
the global atomic state.
Use the drm_atomic_get_old_crtc_state helper to get that state to make it
more obvious.

The current arm64 default config limits max NUMA nodes available on
system to 4 (NODES_SHIFT = 2). Today's arm64 systems can reach or

NODES_SHIFT within page flags on arm64, increase NODES_SHIFT to 4.

Commit 5a18e1e0c193b introduced the 'failover_pending' state to track
the "failover pending window" - where we wait for the partner to become
ready (after a transport event) before actually attempting to failover.
i.e window is between following two events:
a. we get a transport event due to a FAILOVER
b. later, we get CRQ_INITIALIZED indicating the partner is
ready at which point we schedule a FAILOVER reset.
and ->failover_pending is true during this window.
If during this window, we attempt to open (or close) a device, we pretend
that the operation succeded and let the FAILOVER reset path complete the
operation.
This is fine, except if the transport event ("a" above) occurs during the
open and after open has already checked whether a failover is pending. If
that happens, we fail the open, which can cause the boot scripts to leave
the interface down requiring administrator to manually bring up the device.
This fix "extends" the failover pending window till we are _actually_
ready to perform the failover reset (i.e until after we get the RTNL
lock). Since open() holds the RTNL lock, we can be sure that we either
finish the open or if the open() fails due to the failover pending window,
we can again pretend that open is done and let the failover complete it.
We could try and block the open until failover is completed but a) that
could still timeout the application and b) Existing code "pretends" that
failover occurred "just after" open succeeded, so marks the open successful
and lets the failover complete the open. So, mark the open successful even
if the transport event occurs before we actually start the open.

While reenabling the IRQ after irq poll there may be small time window
where HBA firmware has posted some replies and raise the interrupts but
driver has not received the interrupts. So we may observe I/O timeouts as
the driver has not processed the replies as interrupts got missed while
reenabling the IRQ.
To fix this issue the driver has to go for one more round of processing the
reply descriptors from reply descriptor post queue after enabling the IRQ.

alua_bus_detach() might be running concurrently with alua_rtpg_work(), so
we might trip over h->sdev == NULL and call BUG_ON(). The correct way of
handling it is to not set h->sdev to NULL in alua_bus_detach(), and call
rcu_synchronize() before the final delete to ensure that all concurrent
threads have left the critical section. Then we can get rid of the
BUG_ON() and replace it with a simple if condition.

Commit 978aa0474115 ("sctp: fix some type cast warnings introduced since
very beginning")' broke err reading from sctp_arg, because it reads the
value as 32-bit integer, although the value is stored as 16-bit integer.
Later this value is passed to the userspace in 16-bit variable, thus the
user always gets 0 on big-endian platforms. Fix it by reading the __u16
field of sctp_arg union, as reading err field would produce a sparse
warning.

Some of the font tty ioctl's always used the current foreground VC for
their operations. Don't do that then.
This fixes a data race on fg_console.
Side note: both Michael Ellerman and Jiri Slaby point out that all these
ioctls are deprecated, and should probably have been removed long ago,
and everything seems to be using the KDFONTOP ioctl instead.
In fact, Michael points out that it looks like busybox's loadfont
program seems to have switched over to using KDFONTOP exactly _because_
of this bug (ahem.. 12 years ago ;-).

The TI CPTS does not natively support PTPv1, only PTPv2. But, as it
happens, the CPTS can provide HW timestamp for PTPv1 Sync messages, because
CPTS HW parser looks for PTP messageType id in PTP message octet 0 which
value is 0 for PTPv1. As result, CPTS HW can detect Sync messages for PTPv1
and PTPv2 (Sync messageType = 0 for both), but it fails for any other PTPv1
messages (Delay_req/resp) and will return PTP messageType id 0 for them.
The commit e9523a5a32a1 ("net: ethernet: ti: cpsw: enable
HWTSTAMP_FILTER_PTP_V1_L4_EVENT filter") added PTPv1 hw timestamping
advertisement by mistake, only to make Linux Kernel "timestamping" utility
work, and this causes issues with only PTPv1 compatible HW/SW - Sync HW
timestamped, but Delay_req/resp are not.
Hence, fix it disabling PTPv1 hw timestamping advertisement, so only PTPv1
compatible HW/SW can properly roll back to SW timestamping.

parse_synth_field() returns a pointer and requires that errors get
surrounded by ERR_PTR(). The ret variable is initialized to zero, but should
never be used as zero, and if it is, it could cause a false return code and
produce a NULL pointer dereference. It makes no sense to set ret to zero.
Set ret to -ENOMEM (the most common error case), and have any other errors
set it to something else. This removes the need to initialize ret on *every*
error branch.

The recursion protection of the ring buffer depends on preempt_count() to be
correct. But it is possible that the ring buffer gets called after an
interrupt comes in but before it updates the preempt_count(). This will
trigger a false positive in the recursion code.

uses a "transition" bit that gets set, to allow for a single recursion for
to handle transitions between contexts.
