      Pull futex fix from Thomas Gleixner:
       "Fix for yet another subtle futex issue.
      
        The futex code used ihold() to prevent inodes from vanishing, but
        ihold() does not guarantee inode persistence. Replace the inode
        pointer with a per boot, machine wide, unique inode identifier.
      
        The second commit fixes the breakage of the hash mechanism which
        causes a 100% performance regression"

      Pull x86 fixes from Thomas Gleixner:
       "Two fixes for x86:
      
         - Map EFI runtime service data as encrypted when SEV is enabled.
      
           Otherwise e.g. SMBIOS data cannot be properly decoded by dmidecode.
      
         - Remove the warning in the vector management code which triggered
           when a managed interrupt affinity changed outside of a CPU hotplug
           operation.
      
           The warning was correct until the recent core code change that
           introduced a CPU isolation feature which needs to migrate managed
           interrupts away from online CPUs under certain conditions to
           achieve the isolation"

      Pull perf fixes from Thomas Gleixner:
       "A pile of perf fixes:
      
        Kernel side:
      
         - AMD uncore driver: Replace the open coded sanity check with the
           core variant, which provides the correct error code and also leaves
           a hint in dmesg
      
        Tooling:
      
         - Fix the stdio input handling with glibc versions >= 2.28
      
         - Unbreak the futex-wake benchmark which was reduced to 0 test
           threads due to the conversion to cpumaps
      
         - Initialize sigaction structs before invoking sys_sigactio()
      
         - Plug the mapfile memory leak in perf jevents
      
         - Fix off by one relative directory includes

      Pull RAS fixes from Thomas Gleixner:
       "Two RAS related fixes:
      
         - Shut down the per CPU thermal throttling poll work properly when a
           CPU goes offline.
      
           The missing shutdown caused the poll work to be migrated to a
           unbound worker which triggered warnings about the usage of
           smp_processor_id() in preemptible context
      
         - Fix the PPIN feature initialization which missed to enable the
           functionality when PPIN_CTL was enabled but the MSR locked against
           updates"
