       "A set of scheduler updates:
      
         - Prevent a NULL pointer dereference in the migration_stop_cpu()
           mechanims
      
         - Prevent self concurrency of affine_move_task()
      
         - Small fixes and cleanups related to task migration/affinity setting
      
         - Ensure that sync_runqueues_membarrier_state() is invoked on the
           current CPU when it is in the cpu mask"

      Pull locking fixes from Thomas Gleixner:
       "A couple of locking fixes:
      
         - A fix for the static_call mechanism so it handles unaligned
           addresses correctly.
      
         - Make u64_stats_init() a macro so every instance gets a seperate
           lockdep key.
      
         - Make seqcount_latch_init() a macro as well to preserve the static
           variable which is used for the lockdep key"

      Linus Torvalds authored
      Pull perf fixes from Borislav Petkov:
      
       - Make sure PMU internal buffers are flushed for per-CPU events too and
         properly handle PID/TID for large PEBS.
      
       - Handle the case properly when there's no PMU and therefore return an
         empty list of perf MSRs for VMX to switch instead of reading random
         garbage from the stack.

      Pull x86 fixes from Borislav Petkov:
      
       - A couple of SEV-ES fixes and robustifications: verify usermode stack
         pointer in NMI is not coming from the syscall gap, correctly track
         IRQ states in the #VC handler and access user insn bytes atomically
         in same handler as latter cannot sleep.
      
       - Balance 32-bit fast syscall exit path to do the proper work on exit
         and thus not confuse audit and ptrace frameworks.
      
       - Two fixes for the ORC unwinder going "off the rails" into KASAN
         redzones and when ORC data is missing.

      Pull powerpc fixes from Michael Ellerman:
       "Some more powerpc fixes for 5.12:
      
         - Fix wrong instruction encoding for lis in ppc_function_entry(),
           which could potentially lead to missed kprobes.
      
         - Fix SET_FULL_REGS on 32-bit and 64e, which prevented ptrace of
           non-volatile GPRs immediately after exec.
      
         - Clean up a missed SRR specifier in the recent interrupt rework.
      
         - Don't treat unrecoverable_exception() as an interrupt handler, it's
           called from other handlers so shouldn't do the interrupt entry/exit
           accounting itself.
      
         - Fix build errors caused by missing declarations for
           [en/dis]able_kernel_vsx().
