Pull sound fixes from Takashi Iwai:
 "Here are a collection of small fixes tha have been gathered for

  A reverse select is often more user-friendly, but in this case, it
  makes hard to manage with the conflict with ZONE_DEVICE, so changed in
  such a way for now.

  Others are all small fixes and quirks: an error check in soundcore

 "Found a couple of brown paper bag bugs with the prev pull request
  (including a SMP build breakage report from Guenter).  Since these are
  urgent I also decided to send over a bunch of other pending fixes
  which could have otherwise waited an rc or two.

  Summary:

   - A bunch of brown paper bag bugs (MAINTAINERS list email, SMP build
     failure)
   - cpu_relax() now compiler barrier for UP as well
   - handling of userspace Bus Errors for ARCompact builds"

  ARC: use ASL assembler mnemonic
  ARC: [arcompact] Handle bus error from userspace as Interrupt not exception
  ARC: remove extraneous header include
  ARCv2: lib: memcpy: use local symbols

cpu_relax() on ARC has been barrier only for SMP (and no-op for UP). Per
recent discussions, it is safer to make it a compiler barrier
unconditionally.

ARCompact and ARCv2 only have ASL, while binutils used to support LSL as
a alias mnemonic.

Newer binutils (upstream) don't want to do that so replace it.
Signed-off-by: Vineet Gupta <vgupta@synopsys.com>

Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)

 - So move mem_service exception handler from common code into ARCv2 code.
 - In ARCompact code, define  mem_service as L2 interrupt handler which
   just drops down to pure kernel mode and goes of to enqueue SIGBUS

This merge resolution comes from Alexander Shishkin, who updated his stm
class tracing abstraction to account for the removal of the old
show_attribute and store_attribute methods in commit 51798222
("configfs: remove old API") from this pull.  As Alexander says about
that patch:

 "There's no need to keep an extra wrapper structure per item and the
  awkward show_attribute/store_attribute item ops are no longer needed.

  This patch converts policy code to the new api, all the while making
  the code quite a bit smaller and easier on the eyes.

Now that the xattr handler is passed to the xattr handler operations, we
can use the same get and set operations for the user, trusted, and security
xattr namespaces.  In those namespaces, we can access the full attribute
name by "reattaching" the name prefix the vfs has skipped for us.  Add a
xattr_full_name helper to make this obvious in the code.

For the "system.posix_acl_access" and "system.posix_acl_default"
attributes, handler->prefix is the full attribute name; the suffix is the
empty string.

The xattr_handler operations are currently all passed a file system
specific flags value which the operations can use to disambiguate between
different handlers; some file systems use that to distinguish the xattr
namespace, for example.  In some oprations, it would be useful to also have
access to the handler prefix.  To allow that, pass a pointer to the handler
to operations instead of the flags value alone.

When a filesystem that contains POSIX ACLs is mounted without ACL support
(-o noacl), the appropriate behavior is not to list any existing POSIX ACL
xattrs.  The return value for list xattr handlers in this case is 0, not an
error code: several filesystems that use the POSIX ACL xattr handlers do
not expect the list operation to fail.

Symlinks cannot have ACLs, so posix_acl_xattr_list will never be called for

Fix this by falling back to 4K mappings in the pfn_valid() case.  Longer
term, vmf_insert_pfn_pmd() needs to grow support for architectures that
can provide a 'pmd_special' capability.

Rockchip drm can't work with generic drm_of_component_probe now

Seems the crtc helpers call drm_calc_timestamping_constants()
unconditionally even if the driver didn't initialize vblank support by
calling drm_vblank_init(). That used to be OK since the constants were
stored under drm_crtc.

However I broke this with
commit eba1f35d ("drm: Move timestamping constants into drm_vblank_crtc")
when I moved the constants to live inside the drm_vblank_crtc struct
instead. If drm_vblank_init() isn't called, we don't allocate these
structures, and so drm_calc_timestamping_constants() will oops.

Fix it by adding a check into drm_calc_timestamping_constants() to see
if vblank support was initialized at all. And to keep in line with other
such checks, also toss in a check and warn for the case where vblank
support was initialized, but the wrong number of crtcs was specified.

Fixes the following sort of oops:
