      Pull x86 core updates from Borislav Petkov:
      
       - Do not #GP on userspace use of CLI/STI but pretend it was a NOP to
         keep old userspace from breaking. Adjust the corresponding iopl
         selftest to that.
      
       - Improve stack overflow warnings to say which stack got overflowed and
         raise the exception stack sizes to 2 pages since overflowing the
         single page of exception stack is very easy to do nowadays with all
         the tracing machinery enabled. With that, rip out the custom mapping
         of AMD SEV's too.
      
       - A bunch of changes in preparation for FGKASLR like supporting more
         than 64K section headers in the relocs tool, correct ORC lookup table
         size to cover the whole kernel .text and other adjustments.

      Pull selinux updates from Paul Moore:
      
       - Add LSM/SELinux/Smack controls and auditing for io-uring.
      
         As usual, the individual commit descriptions have more detail, but we
         were basically missing two things which we're adding here:
      
            + establishment of a proper audit context so that auditing of
              io-uring ops works similarly to how it does for syscalls (with
              some io-uring additions because io-uring ops are *not* syscalls)
      
            + additional LSM hooks to enable access control points for some of
              the more unusual io-uring features, e.g. credential overrides.
      
         The additional audit callouts and LSM hooks were done in conjunction
         with the io-uring folks, based on conversations and RFC patches
         earlier in the year.
      
       - Fixup the binder credential handling so that the proper credentials
         are used in the LSM hooks; the commit description and the code
         comment which is removed in these patches are helpful to understand
         the background and why this is the proper fix.
      
       - Enable SELinux genfscon policy support for securityfs, allowing
         improved SELinux filesystem labeling for other subsystems which make
         use of securityfs, e.g. IMA.

      Merge tag 'rcu.2021.11.01a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu · 6fedc280
      Linus Torvalds authored
      Pull RCU updates from Paul McKenney:
      
       - Miscellaneous fixes
      
       - Torture-test updates for smp_call_function(), most notably improved
         checking of module parameters.
      
       - Tasks-trace RCU updates that fix a number of rare but important
         race-condition bugs.
      
       - Other torture-test updates, most notably better checking of module
         parameters. In addition, rcutorture may once again be run on
         CONFIG_PREEMPT_RT kernels.
      
       - Torture-test scripting updates, most notably specifying the new
         CONFIG_KCSAN_STRICT kconfig option rather than maintaining an
         ever-changing list of individual KCSAN kconfig options.
