Linus Torvalds 12b76f3bf3 sound fixes for 4.4-rc1
Here are a collection of small fixes tha have been gathered for
 4.4-rc1.  The only significant changes are those in PCI drivers
 Kconfig, to use "depends on" instead of "select" for CONFIG_ZONE_DMA.
 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
 reigster_chrdev(), HD-audio HDMI/DP phantom jack fix, Intel Broxton DP
 quirk, USB-audio DSD device quirk, some constifications, etc.

Vineet Gupta 1cfc05cbe2 ARC: cpu_relax() to be compiler barrier even for UP
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.

Vineet Gupta a6416f57ce ARC: use ASL assembler mnemonic
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.

Vineet Gupta 541366da6a ARC: [arcompact] Handle bus error from userspace as Interrupt not exception
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

Linus Torvalds 63f4f7e8df platform/chrome: Branch for v4.4
Here's the branch of chrome platform changes for v4.4. Some have been queued
 up for the full 4.3 release cycle since I forgot to send them in for that
 round (rebased early on to deal with fixes conflicts).
 
 Most of these enable EC communication stuff -- Pixel 2015 support, enabling
 building for ARM64 platforms, and a few fixes for memory leaks.
 
 There's also a patch in here to allow reading/writing the verified boot
 context, which depends on a sysfs patch acked by Greg.

 "This series contains HCH's changes to absorb configfs attribute
  ->show() + ->store() function pointer usage from it's original
  tree-wide consumers, into common configfs code.

  It includes usb-gadget, target w/ drivers, netconsole and ocfs2
  changes to realize the improved simplicity, that now renders the
  original include/target/configfs_macros.h CPP magic for fabric drivers
  and others, unnecessary and obsolete.

  And with common code in place, new configfs attributes can be added
  easier than ever before.

  Note, there are further improvements in-flight from other folks for
  v4.5 code in configfs land, plus number of target fixes for post -rc1
  code"

In the meantime, a new user of the now-removed old configfs API came in
through the char/misc tree in commit 7bd1d4093c ("stm class: Introduce
an abstraction for System Trace Module devices").

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 517982229f
("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.

Andreas Gruenbacher e409de992e 9p: xattr simplifications
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.

Andreas Gruenbacher d9a82a0403 xattr handlers: Pass handler to operations instead of flags
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.

Andreas Gruenbacher dae5f57a72 vfs: Fix the posix_acl_xattr_list return value
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
symlinks in the first place.
