#     Merge branch 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 pti updates from Thomas Gleixner:
#      "No point in speculating what's in this parcel:
#     
#        - Drop the swap storage limit when L1TF is disabled so the full space
#          is available
#     
#        - Add support for the new AMD STIBP always on mitigation mode
#     
#        - Fix a bunch of STIPB typos"
#     
#     * 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
#       x86/speculation: Add support for STIBP always-on preferred mode
#       x86/speculation/l1tf: Drop the swap storage limit restriction when l1tf=off
#       x86/speculation: Change misspelled STIPB to STIBP
