4c0716ee1d crypto: sa2ul - Fix leaks on failure paths with sa_dma_init()
The sa_dma_init() function doesn't release the requested dma channels
on all failure paths. Any failure in this function also ends up
leaking the dma pool created in sa_init_mem() in the sa_ul_probe()
function. Fix all of these issues.

dfb098d692 crypto: ixp4xx - fallback when having more than one SG
Testing ixp4xx_crypto lead to:
alg: skcipher: ecb(des)-ixp4xx encryption overran dst buffer on test vector 0, cfg="two even aligned splits"

The HW overwrites destination always when sg_nents() > 1.
The problem seems that the HW always write areq->cryptlen bytes on the
last SG.
A comment in driver's code seems to give a clue that multiple SG was not
planned "This was never tested by Intel for more than one dst buffer, I think".
So let's add a fallback for this situation.

6c34e446b2 crypto: qce - Make result dump optional
Qualcomm crypto engine allows for IV registers and status register
to be concatenated to the output. This option is enabled by setting the
RESULTS_DUMP field in GOPROC  register. This is useful for most of the
algorithms to either retrieve status of operation or in case of
authentication algorithms to retrieve the mac. But for ccm
algorithms, the mac is part of the output stream and not retrieved
from the IV registers, thus needing a separate buffer to retrieve it.
Make enabling RESULTS_DUMP field optional so that algorithms can choose
whether or not to enable the option.
Note that in this patch, the enabled algorithms always choose
RESULTS_DUMP to be enabled. But later with the introduction of ccm
algorithms, this changes.

6dae40aed4 fbmem: fix horribly incorrect placement of __maybe_unused
Commit b9d79e4ca4 ("fbmem: Mark proc_fb_seq_ops as __maybe_unused")
places the '__maybe_unused' in an entirely incorrect location between
the "struct" keyword and the structure name.

It's a wonder that gcc accepts that silently, but clang quite reasonably
warns about it:

    drivers/video/fbdev/core/fbmem.c:736:21: warning: attribute declaration must precede definition [-Wignored-attributes]
    static const struct __maybe_unused seq_operations proc_fb_seq_ops = {

9819f682e4 A set of scheduler updates:
- Prevent PSI state corruption when schedule() races with cgroup move.  A
    recent commit combined two PSI callbacks to reduce the number of cgroup
    tree updates, but missed that schedule() can drop rq::lock for load
    balancing, which opens the race window for cgroup_move_task() which then
    observes half updated state. The fix is to solely use task::ps_flags
    instead of looking at the potentially mismatching scheduler state
 
  - Prevent an out-of-bounds access in uclamp caused bu a rounding division
    which can lead to an off-by-one error exceeding the buckets array size.
 
  - Prevent unfairness caused by missing load decay when a task is attached
    to a cfs runqueue. The old load of the task is attached to the runqueue
    and never removed. Fix it by enforcing the load update through the
    hierarchy for unthrottled run queue instances.
 
  - A documentation fix fot the 'sched_verbose' command line option
