Linus Torvalds 4e3c09e954 v6.5-rc1-modules-next
The changes queued up for v6.5-rc1 for modules are pretty tame, mostly
 code removal of moving of code. Only two minor functional changes are
 made, the only one which stands out is Sebastian Andrzej Siewior's
 simplification of module reference counting by removing preempt_disable()
 and that has been tested on linux-next for well over a month without
 no regressions. I'm now, I guess, also a kitchen sink for some kallsyms
 changes.

Merge tag 'v6.5-rc1-modules-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux

Pull module updates from Luis Chamberlain:
 "The changes queued up for modules are pretty tame, mostly code removal
  of moving of code.

  Only two minor functional changes are made, the only one which stands
  out is Sebastian Andrzej Siewior's simplification of module reference
  counting by removing preempt_disable() and that has been tested on
  linux-next for well over a month without no regressions.

[ There was a mis-communication about the concurrent module load changes
  that I had expected to come through Luis despite me authoring the
  patch. So some of the module updates were left hanging in the email
  ether, and I just committed them separately.

  It's my bad - I should have made it more clear that I expected my
  own patches to come through the module tree too. Now they missed
  linux-next, but hopefully that won't cause any issues    - Linus ]

* tag 'v6.5-rc1-modules-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux:
  kallsyms: make kallsyms_show_value() as generic function
  kallsyms: move kallsyms_show_value() out of kallsyms.c
  kallsyms: remove unsed API lookup_symbol_attrs
  kallsyms: remove unused arch_get_kallsym() helper
  module: Remove preempt_disable() from module reference counting.
