36e630ed98 Driver core fixes for 5.3-rc4
Here are 2 small fixes for some driver core issues that have been
 reported.  There is also a kernfs "fix" here, which was then reverted
 because it was found to cause problems in linux-next.
 
 The driver core fixes both resolve reported issues, one with gpioint
 stuff that showed up in 5.3-rc1, and the other finally (and hopefully)
 resolves a very long standing race when removing glue directories.  It's
 nice to get that issue finally resolved and the developers involved
 should be applauded for the persistence it took to get this patch
 finally accepted.
 
 All of these have been in linux-next for a while with no reported
 issues.  Well, the one reported issue, hence the revert :)

c13f86701e TTY fix for 5.3-rc4
Here is a single tty kgdb fix for 5.3-rc4.
 
 It fixes an annoying log message that has caused kdb to become useless.
 It's another fallout from ddde3c18b7 ("vt: More locking checks") which
 tries to enforce locking checks more strictly in the tty layer,
 unfortunatly when kdb is stopped, there's no need for locks :)
 
 This patch has been linux-next for a while with no reported issues

1041f50921 USB fixes for 5.3-rc4
Here are some small USB fixes for 5.3-rc4.
 
 The "biggest" one here is moving code from one file to another in order
 to fix a long-standing race condition with the creation of sysfs files
 for USB devices.  Turns out that there are now userspace tools out there
 that are hitting this long-known bug, so it's time to fix them.
 Thankfully the tool-maker in this case fixed the issue :)
 
 The other patches in here are all fixes for reported issues.  Now that
 syzbot knows how to fuzz USB drivers better, and is starting to now fuzz
 the userspace facing side of them at the same time, there will be more
 and more small fixes like these coming, which is a good thing.
 
 All of these have been in linux-next with no reported issues.

06282373ff mm/memremap: Fix reuse of pgmap instances with internal references
Currently, attempts to shutdown and re-enable a device-dax instance
trigger:

    Missing reference count teardown definition

Given that the setup path initializes pgmap->ref, arrange for it to be

not be mistaken for the 3rd-party per-cpu-ref case.

e6a9522ac3 drm/i915: Remove redundant user_access_end() from __copy_from_user() error path
Objtool reports:

  drivers/gpu/drm/i915/gem/i915_gem_execbuffer.o: warning: objtool: .altinstr_replacement+0x36: redundant UACCESS disable

__copy_from_user() already does both STAC and CLAC, so the
user_access_end() in its error path adds an extra unnecessary CLAC.

c07d8d47bc kbuild: show hint if subdir-y/m is used to visit module Makefile
Since commit ff9b45c55b ("kbuild: modpost: read modules.order instead
of $(MODVERDIR)/*.mod"), a module is no longer built in the following
pattern:

  [Makefile]
  subdir-y := some-module

  [some-module/Makefile]
  obj-m := some-module.o

You cannot write Makefile this way in upstream because modules.order is
not correctly generated. subdir-y is used to descend to a sub-directory
that builds tools, device trees, etc.

For external modules, the modules order does not matter. So, the
Makefile above was known to work.

I believe the Makefile should be re-written as follows:

  [Makefile]
  obj-m := some-module/

  [some-module/Makefile]
  obj-m := some-module.o

However, people will have no idea if their Makefile suddenly stops
working. In fact, I received questions from multiple people.

Show a warning for a while if obj-m is specified in a Makefile visited
by subdir-y or subdir-m.

I touched the %/ rule to avoid false-positive warnings for the single
target.

4f2c8f3089 kbuild: generate modules.order only in directories visited by obj-y/m
The modules.order files in directories visited by the chain of obj-y
or obj-m are merged to the upper-level ones, and become parts of the
top-level modules.order. On the other hand, there is no need to
generate modules.order in directories visited by subdir-y or subdir-m
since they would become orphan anyway.

47801c97de kbuild: revive single target %.ko
I removed the single target %.ko in commit ff9b45c55b ("kbuild:
modpost: read modules.order instead of $(MODVERDIR)/*.mod") because
the modpost stage does not work reliably. For instance, the module
dependency, modversion, etc. do not work if we lack symbol information
from the other modules.

Yet, some people still want to build only one module in their interest,
and it may be still useful if it is used within those limitations.

Lots of small fixes at this time since we've received the ASoC
 fix batch now.
 
 - Some coverage in ASoC core mostly for minor issues like NULL
   checks for DPCM and proper error handling in DAI instantiation
 
 - A collection of small device-specific changes in various ASoC
   codec and platform drivers
 
 - OF-tree refcount fixes in a few ASoC drivers
 
 - Fixes of memory leaks in the error paths of various ASoC / ALSA
   drivers
 
 - A workaround for a long-standing issue on AMD HD-audio device
 
 - Updates of MAINTAINERS, mail addresses, file permission fixups

a27a0c9b6a gfs2: gfs2_walk_metadata fix
It turns out that the current version of gfs2_metadata_walker suffers
from multiple problems that can cause gfs2_hole_size to report an
incorrect size.  This will confuse fiemap as well as lseek with the
SEEK_DATA flag.

Fix that by changing gfs2_hole_walker to compute the metapath to the
first data block after the hole (if any), and compute the hole size
based on that.

Fixes xfstest generic/490.
