Pull arm64 fixes from Will Deacon:
 "Three arm64 fixes for -rc4.

  One of them is just a trivial documentation fix, whereas the other two
  address a warning in the kexec code and a crash in ftrace on systems
  implementing BTI.

  The latter patch has a couple of ugly ifdefs which Mark plans to clean
  up separately, but as-is the patch is straightforward for backporting
  to stable kernels.

  Summary:

   - Add missing BTI landing instructions to the ftrace*_caller

   - Fix kexec() WARN when DEBUG_VIRTUAL is enabled

   - Fix PAC documentation by removing stale references to compiler
     flags"

6a631c0432 Documentation/locking/locktypes: Update migrate_disable() bits.
The initial implementation of migrate_disable() for mainline was a
wrapper around preempt_disable(). RT kernels substituted this with
a real migrate disable implementation.

Later on mainline gained true migrate disable support, but the
documentation was not updated.

Update the documentation, remove the claims about migrate_disable()
mapping to preempt_disable() on non-PREEMPT_RT kernels.

5c81691bb6 docs: admin-guide/blockdev: Remove digraph of node-states
While node-states-8.dot has two digraphs, the dot(1) command can
not properly handle multiple graphs in a DOT file and the
kernel-doc page at

    https://www.kernel.org/doc/html/latest/admin-guide/blockdev/drbd/figures.html

fails to render the graphs.

It turned out that the digraph of node_states can be removed.

Quote from Joel's reflection:

    On reflection, the digraph node_states can be removed entirely.
    It is too basic to contain any useful information. In addition
    it references "ioctl_set_state". The ioctl configuration
    interface for DRBD has long been removed. In fact, it was never
    in the upstream version of DRBD.

Remove node_states and rename the DOT file peer_states-8.dot.

d69dab7de2 docs: conf.py: fix support for Readthedocs v 1.0.0
As described at:
	https://stackoverflow.com/questions/23211695/modifying-content-width-of-the-sphinx-theme-read-the-docs

since Sphinx 1.8, the standard way to setup a custom theme is
to use html_css_files. While using html_context is OK with RTD
0.5.2, it doesn't work with 1.0.0, causing the theme to not load,
producing a very weird html.

Tested with:
	- Sphinx 1.7.9 + sphinx-rtd-theme 0.5.2
	- Sphinx 2.4.4 + sphinx-rtd-theme 0.5.2
	- Sphinx 2.4.4 + sphinx-rtd-theme 1.0.0
	- Sphinx 4.3.0 + sphinx-rtd-theme 1.0.0

1aa3b2207e net,lsm,selinux: revert the security_sctp_assoc_established() hook
This patch reverts two prior patches, e7310c9402
("security: implement sctp_assoc_established hook in selinux") and
7c2ef0240e ("security: add sctp_assoc_established hook"), which
create the security_sctp_assoc_established() LSM hook and provide a
SELinux implementation.  Unfortunately these two patches were merged
without proper review (the Reviewed-by and Tested-by tags from
Richard Haines were for previous revisions of these patches that
were significantly different) and there are outstanding objections
from the SELinux maintainers regarding these patches.

Work is currently ongoing to correct the problems identified in the
reverted patches, as well as others that have come up during review,
but it is unclear at this point in time when that work will be ready
for inclusion in the mainline kernel.  In the interest of not keeping
objectionable code in the kernel for multiple weeks, and potentially
a kernel release, we are reverting the two problematic patches.

Merge tag 'selinux-pr-20211112' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux fixes from Paul Moore:
 "Unfortunately I need to request a revert for two LSM/SELinux patches
  that came in via the network tree. The two patches in question add a
  new SCTP/LSM hook as well as an SELinux implementation of that LSM
  hook. The short version of "why?" is in the commit description of the
  revert patch, but I'll copy-n-paste the important bits below to save
  some time for the curious:

      ... Unfortunately these two patches were merged without proper
      review (the Reviewed-by and Tested-by tags from Richard Haines
      were for previous revisions of these patches that were
      significantly different) and there are outstanding objections from
      the SELinux maintainers regarding these patches.

      Work is currently ongoing to correct the problems identified in
      the reverted patches, as well as others that have come up during
      review, but it is unclear at this point in time when that work
      will be ready for inclusion in the mainline kernel. In the
      interest of not keeping objectionable code in the kernel for
      multiple weeks, and potentially a kernel release, we are reverting
      the two problematic patches.

  As usual with these things there is plenty of context to go with this
  and I'll try to do my best to provide that now. This effort started
  with a report of SCTP client side peel-offs not working correctly with
  SELinux, Ondrej Mosnacek put forth a patch which he believed properly
  addressed the problem but upon review by the netdev folks Xin Long
  described some additional issues and submitted an improved patchset
  for review. The SELinux folks reviewed Xin Long's initial patchset and
  suggested some changes which resulted in a second patchset (v2) from
  Xin Long; this is the patchset that is currently in your tree.
  Unfortunately this v2 patchset from Xin Long was merged before it had
  spent even just 24 hours on the mailing lists during the early days of
  the merge window, a time when many of us were busy doing verification
  of the newly released v5.15 kernel as well final review and testing of
  our v5.16 pull requests. Making matters worse, upon reviewing the v2
  patchset there were both changes which were found objectionable by
  SELinux standards as well as additional outstanding SCTP/SELinux
  interaction problems. At this point we did two things: resumed working
  on a better fix for the SCTP/SELinux issue(s) - thank you Ondrej - and
  we asked the networking folks to revert the v2 patchset.

  The revert request was obviously rejected, but at the time I believed
  it was just going to be an issue for linux-next; I wasn't expecting
  something this significant that was merged into the networking tree
  during the merge window to make it into your tree in the same window,
  yet as of last night that is exactly what happened. While we continue
  to try and resolve the SCTP/SELinux problem I am asking once again to
  revert the v2 patches and not ship the current
  security_sctp_assoc_established() hook in a v5.16-rcX kernel. If I was
  confident that we could solve these issues in a week, maybe two, I
  would refrain from asking for the revert but our current estimate is
  for a minimum of two weeks for the next patch revision. With the
  likelihood of additional delays due to normal patch review follow-up
  and/or holidays it seems to me that the safest course of action is to
  revert the patch both to try and keep some objectionable code out of a
  release kernel and limit the chances of any new breakages from such a
  change. While the SCTP/SELinux code in v5.15 and earlier has problems,
  they are known problems, and I'd like to try and avoid creating new
  and different problems while we work to fix things properly.

  One final thing to mention: Xin Long's v2 patchset consisted of four
  patches, yet this revert is for only the last two. We see the first
  two patches as good, reasonable, and not likely to cause an issue. In
  an attempt to create a cleaner revert patch we suggest leaving the
  first two patches in the tree as they are currently"

Merge tag 'rtc-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "This includes new ioctls to get and set parameters and in particular
  the backup switch mode that is needed for some RTCs to actually enable
  the backup voltage (and have a useful RTC).

  failing.

32a370abf1 net,lsm,selinux: revert the security_sctp_assoc_established() hook
This patch reverts two prior patches, e7310c9402
("security: implement sctp_assoc_established hook in selinux") and
7c2ef0240e ("security: add sctp_assoc_established hook"), which
create the security_sctp_assoc_established() LSM hook and provide a
SELinux implementation.  Unfortunately these two patches were merged
without proper review (the Reviewed-by and Tested-by tags from
Richard Haines were for previous revisions of these patches that
were significantly different) and there are outstanding objections
from the SELinux maintainers regarding these patches.

Work is currently ongoing to correct the problems identified in the
reverted patches, as well as others that have come up during review,
but it is unclear at this point in time when that work will be ready
for inclusion in the mainline kernel.  In the interest of not keeping
objectionable code in the kernel for multiple weeks, and potentially
a kernel release, we are reverting the two problematic patches.

Support for Netlogic was removed in commit 95b8a5e011 ("MIPS: Remove
NETLOGIC support"). Remove the now unused bindings.

The GPIO binding also includes "brcm,vulcan-gpio", but it appears to be
unused as well as Broadcom Vulkan became Cavium ThunderX2 which is ACPI
based.
