In some cases, when password2 becomes the working password, the
client swaps the two password fields in the root session struct, but
not in the smb3_fs_context struct in cifs_sb. DFS automounts inherit
fs context from their parent mounts. Therefore, they might end up
getting the passwords in the stale order.
The automount should succeed, because the mount function will end up
retrying with the actual password anyway. But to reduce these
unnecessary session setup retries for automounts, we can sync the
parent context's passwords with the root session's passwords before
duplicating it to the child's fs context.

With the consolidation of put_prev_task/set_next_task(), see
commit 436f3eed5c ("sched: Combine the last put_prev_task() and the
first set_next_task()"), we are now skipping the transition between
these two functions when the previous and the next tasks are the same.
As a result, the scx idle state of a CPU is updated only when
transitioning to or from the idle thread. While this is generally
correct, it can lead to uneven and inefficient core utilization in
certain scenarios [1].
A typical scenario involves proactive wake-ups: scx_bpf_pick_idle_cpu()
selects and marks an idle CPU as busy, followed by a wake-up via
scx_bpf_kick_cpu(), without dispatching any tasks. In this case, the CPU
continues running the idle thread, returns to idle, but remains marked
as busy, preventing it from being selected again as an idle CPU (until a
task eventually runs on it and releases the CPU).
For example, running a workload that uses 20% of each CPU, combined with
an scx scheduler using proactive wake-ups, results in the following core
utilization:
CPU 0: 25.7%
CPU 1: 29.3%
CPU 2: 26.5%
CPU 3: 25.5%
CPU 4: 0.0%
CPU 5: 25.5%
CPU 6: 0.0%
CPU 7: 10.5%
To address this, refresh the idle state also in pick_task_idle(), during
idle-to-idle transitions, but only trigger ops.update_idle() on actual
state changes to prevent unnecessary updates to the scx scheduler and
maintain balanced state transitions.
With this change in place, the core utilization in the previous example
becomes the following:
CPU 0: 18.8%
CPU 1: 19.4%
CPU 2: 18.0%
CPU 3: 18.7%
CPU 4: 19.3%
CPU 5: 18.9%
CPU 6: 18.7%
CPU 7: 19.3%

With IORING_SETUP_SQPOLL all requests are created by the SQPOLL task,
which means that req->task should always match sqd->thread. Since
accesses to sqd->thread should be separately protected, use req->task
in io_req_normal_work_add() instead.
Note, in the eyes of io_req_normal_work_add(), the SQPOLL task struct
is always pinned and alive, and sqd->thread can either be the task or
NULL. It's only problematic if the compiler decides to reload the value
after the null check, which is not so likely.

delayed_work submitted to an offlined cpu, will not get executed,
after the specified delay if the cpu remains offline. If the cpu
never comes online the work will never get executed.
checking for online cpu in __queue_delayed_work, does not sound
like a good idea because to do this reliably we need hotplug lock
and since work may be submitted from atomic contexts, we would
have to use cpus_read_trylock. But if trylock fails we would queue
the work on any cpu and this may not be optimal because our intended
cpu might still be online.
Putting a WARN_ON_ONCE for an already offlined cpu, will indicate users
of queue_delayed_work_on, if they are (wrongly) trying to queue
delayed_work on offlined cpu. Also indicate the problem of using
offlined cpu with queue_delayed_work_on, in its description.

Now that poll_wait() provides a full barrier we can remove smp_mb() from
sock_poll_wait().
Also, the poll_does_not_wait() check before poll_wait() just adds the
unnecessary confusion, kill it. poll_wait() does the same "p && p->_qproc"
check.

Now that poll_wait() provides a full barrier we can remove smp_rmb() from
io_uring_poll().
In fact I don't think smp_rmb() was correct, it can't serialize LOADs and
STOREs.

This check is historical and no longer needed, wait_address is never NULL.
These days we rely on the poll_table->_qproc check. NULL if select/poll
is not going to sleep, or it already has a data to report, or all waiters
have already been registered after the 1st iteration.
However, poll_table *p can be NULL, see p9_fd_poll() for example, so we
can't remove the "p != NULL" check.

As the comment above waitqueue_active() explains, it can only be used
if both waker and waiter have mb()'s that pair with each other. However
__pollwait() is broken in this respect.
This is not pipe-specific, but let's look at pipe_poll() for example:
poll_wait(...); // -> __pollwait() -> add_wait_queue()
LOAD(pipe->head);
LOAD(pipe->head);
In theory these LOAD()'s can leak into the critical section inside
add_wait_queue() and can happen before list_add(entry, wq_head), in this
case pipe_poll() can race with wakeup_pipe_readers/writers which do
smp_mb();
if (waitqueue_active(wq_head))
wake_up_interruptible(wq_head);
There are more __pollwait()-like functions (grep init_poll_funcptr), and
it seems that at least ep_ptable_queue_proc() has the same problem, so the
patch adds smp_mb() into poll_wait().

Here are two minor improvement/fixes in the PMU event path. The first patch
was part of the series[1]. The 2nd patch was suggested during the series
review.
While the series can only be merged once SBI v3.0 is frozen, these two
patches can be independent of SBI v3.0 and can be merged sooner. Hence, these
two patches are sent as a separate series.

The SBI specification allows only lower 48bits of hpmeventX to be
configured via SBI PMU. Currently, the driver masks of the higher
bits but doesn't return an error. This will lead to an additional
SBI call for config matching which should return for an invalid
event error in most of the cases.
However, if a platform(i.e Rocket and sifive cores) implements a
bitmap of all bits in the event encoding this will lead to an
incorrect event being programmed leading to user confusion.
Report the error to the user if higher bits are set during the
event mapping itself to avoid the confusion and save an additional
SBI call.

If the upper two bits has an invalid valid (0x1), the event mapping
is not reliable as it returns an uninitialized variable.
Return appropriate value for the default case.

Platform firmware event data field is allowed to be 62 bits for
Linux as uppper most two bits are reserved to indicate SBI fw or
platform specific firmware events.
However, the event data field is masked as per the hardware raw
event mask which is not correct.
Fix the platform firmware event data field with proper mask.

This contains a pair of fixes for the vector self tests, which avoids
some warnings and provides proper status messages.
