 - Stop setting PF_NO_SETAFFINITY on io-wq workers.

   This has been reported in the past as it confuses some applications,

   with io-wq workers active will fail.

   Just deal with the mask changing by checking when a worker times out,
   and then exit if we have no work pending.

 - Fix an issue with passthrough support where we don't properly check
   if the file type has pollable uring_cmd support.

   special helper for iterating these lists that doesn't save the

We're currently using stop_machine() to update ftrace & kprobes, which
means that the thread that takes text_mutex during may not be the same
as the thread that eventually patches the code.  This isn't actually a
race because the lock is still held (preventing any other concurrent
accesses) and there is only one thread running during stop_machine(),
but it does trigger a lockdep failure.

This patch just elides the lockdep check during stop_machine.

msm-fixes for v6.3-rc2

- Fix for possible invalid ptr free in submit ioctl syncobj cleanup path.
- Synchronize GMU removal in driver teardown path
- a5xx preemption fixes
- Fix runpm imbalance at unbind
- DPU hw catalog fixes:
 - set DPU_MDP_PERIPH_0_REMOVED for sc8280xp as this is another chipset
   where the PERIPH_0 block of registers is not there
 - fix the DPU features supported in QCM2290 by comparing it with the
   downstream device tree
 - fix the length of registers in the sc7180_ctl from 0xe4 to 0x1dc
 - fix the max mixer line width for sm6115 and qcm2290 chipsets in the
   DPU catalog
 - fix the scaler version on sm8550, sc8280xp, sm8450, sm8250, sm8350
   and sm6115. This was incorrectly populated on the SW version of the
   scaler library and  not the scaler HW version
 - Drop dim layer support for msm8998 as its not indicated to be
   supported in the downstream DTSI
 - fix the DPU_CLK_CTRL bits for msm 8998 sspp blocks
 - Use DPU_CLK_CTRL_DMA* prefix instead of DPU_CLK_CTRL_CURSOR*
   for all chipsets for the DMA sspp blocks
 - fix the ping-pong block base address for sc7280 in the DPU HW catalog
- Fix stack corruption issue in the dpu_hw_ctl_setup_blendstage() function
  as it was causing a negative left shift by protecting against an invalid
  index
- Clear the DSPP reservations in dpu_rm_release(). This was missed out and
  as as result the DSPP was not released from the resource manager global
  state.

If io_uring.o is built with W=1, it triggers a warning:

io_uring/io_uring.c: In function ‘__io_submit_flush_completions’:
io_uring/io_uring.c:1502:40: warning: variable ‘prev’ set but not used [-Wunused-but-set-variable]

      |                                        ^~~~

which is due to the wq_list_for_each() iterator always keeping a 'prev'
variable. Most users need this to remove an entry from a list, for
example, but __io_submit_flush_completions() never does that.

Add a basic helper that doesn't track prev instead, and use that in
that function.

It's possible for a file type to support uring commands, but not
pollable ones. Hence before issuing one of those, we should check
that it is supported and error out upfront if it isn't.

Let's revert commit 12724ba3 ("erofs: fix kvcalloc() misuse with
__GFP_NOFAIL") since kvmalloc() already supports __GFP_NOFAIL in commit
a421ef30 ("mm: allow !GFP_KERNEL allocations for kvmalloc").  So
the original fix was wrong.

Actually there was some issue as [1] discussed, so before that mm fix
is landed, the warn could still happen but applying this commit first
will cause less.

Lorenzo points out that the generic CLI is broken for the netdev
family. When I added the support for documentation of enums
(and sparse enums) the client script was not updated.
It expects the values in enum to be a list of names,
now it can also be a dict (YAML object).

When sock_alloc_file fails to allocate a file, it will call sock_release.
__sys_socket_file should then not call sock_release again, otherwise there
