#     
#     Pull x86 fixes from Ingo Molnar:
#      "Two fixes:
#     
#        - Fix build failure on Ubuntu with new GCC packages that turn
#          on -fcf-protection
#     
#        - Fix SME memory encryption PTE encoding bug - AFAICT the code
#          worked on 4K page sizes (level 1) but had the wrong shift at
#          higher page level orders (level 2 and higher)"

#       x86/build: Turn off -fcf-protection for realmode targets
