"Regular weekly fixes, this has the usual amdgpu/xe/i915 bits.
There is a bigger bunch of mediatek patches that I considered not
including at this stage, but all the changes (except for one were
obvious small fixes, and the rotation one is a few lines, and I
suppose will help someone have their screen up the right way), I
decided to include it since I expect it got slowed down by holidays
etc, and it's not that mainstream a hw platform.

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.

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.

====================
net: sysctl: avoid using current->nsproxy
As pointed out by Al Viro and Eric Dumazet in [1], using the 'net'
structure via 'current' is not recommended for different reasons:
- Inconsistency: getting info from the reader's/writer's netns vs only
from the opener's netns as it is usually done. This could cause
unexpected issues when other operations are done on the wrong netns.
- current->nsproxy can be NULL in some cases, resulting in an 'Oops'
(null-ptr-deref), e.g. when the current task is exiting, as spotted by
syzbot [1] using acct(2).
The 'net' or 'pernet' structure can be obtained from the table->data
using container_of().
Note that table->data could also be used directly in more places, but
that would increase the size of this fix to replace all accesses via
'net'. Probably best to avoid that for fixes.
Patches 2-9 remove access of net via current->nsproxy in sysfs handlers
in MPTCP, SCTP and RDS. There are multiple patches doing almost the same
thing, but the reason is to ease the backports.
Patch 1 is not directly linked to this, but it is a small fix for MPTCP
available_schedulers sysctl knob to explicitly mark it as read-only.
Please note that this series does not address Al's comment [2]. In SCTP,
some sysctl knobs set other sysfs-exposed variables for the min/max: two
processes could then write two linked values at the same time, resulting
in new values being outside the new boundaries. It would be great if
SCTP developers can look at this problem.

- current->nsproxy can be NULL in some cases, resulting in an 'Oops'
(null-ptr-deref), e.g. when the current task is exiting, as spotted by
syzbot [1] using acct(2).
The 'net' structure can be obtained from the table->data using
container_of().
Note that table->data could also be used directly, but that would
increase the size of this fix, while 'sctp.ctl_sock' still needs to be
retrieved from 'net' structure.

As mentioned in a previous commit of this series, using the 'net'
structure via 'current' is not recommended for different reasons:
- Inconsistency: getting info from the reader's/writer's netns vs only
from the opener's netns.
- current->nsproxy can be NULL in some cases, resulting in an 'Oops'
(null-ptr-deref), e.g. when the current task is exiting, as spotted by
syzbot [1] using acct(2).
The 'net' structure can be obtained from the table->data using
container_of().
Note that table->data could also be used directly, as this is the only
member needed from the 'net' structure, but that would increase the size
of this fix, to use '*data' everywhere 'net->sctp.rto_min/max' is used.

'net.mptcp.available_schedulers' sysctl knob is there to list available
schedulers, not to modify this list.
There are then no reasons to give write access to it.
Nothing would have been written anyway, but no errors would have been
returned, which is unexpected.

I tried a couple of things to reinvigorate the stmmac maintainers
over the last few years but with little effect. The maintainers
are not active, let the MAINTAINERS file reflect reality.
The Synopsys IP this driver supports is very popular we need
a solid maintainer to deal with the complexity of the driver.
