Pull x86 fixes from Thomas Gleixner:
 "A small set of fixes:

   - UAPI data type correction for hyperv

   - correct the cpu cores field in /proc/cpuinfo on CPU hotplug

   - return proper error code in the resctrl file system failure path to
     avoid silent subsequent failures

   - correct a subtle accounting issue in the new vector allocation code
     which went unnoticed for a while and caused suspend/resume
     failures"

Pull NFS client bugfixes from Trond Myklebust:

 - fix a broken cast in nfs4_callback_recallany()

 - fix an Oops during NFSv4 migration events

Pull powerpc fixes from Michael Ellerman:

 - Add handling for a missing instruction in our 32-bit BPF JIT so that
   it can be used for seccomp filtering.

 - Add a missing NULL pointer check before a function call in new EEH
   code.

 - Fix an error path in the new ocxl driver to correctly return EFAULT.

 - The support for the new ibm,drc-info device tree property turns out
   to need several fixes, so for now we just stop advertising to
   firmware that we support it until the bugs can be ironed out.

 - One fix for the new drmem code which was incorrectly modifying the
   device tree in place.

 - Finally two fixes for the RFI flush support, so that firmware can
   advertise to us that it should be disabled entirely so as not to
   affect performance.

Thanks to: Bharata B Rao, Frederic Barrat, Juan J. Alvarez, Mark Lord,
Michael Bringmann.
