#     Merge tag 'x86_core_for_v5.16_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 core updates from Borislav Petkov:
#     
#      - Do not #GP on userspace use of CLI/STI but pretend it was a NOP to
#        keep old userspace from breaking. Adjust the corresponding iopl
#        selftest to that.
#     
#      - Improve stack overflow warnings to say which stack got overflowed and
#        raise the exception stack sizes to 2 pages since overflowing the
#        single page of exception stack is very easy to do nowadays with all
#        the tracing machinery enabled. With that, rip out the custom mapping
#        of AMD SEV's too.
#     
#      - A bunch of changes in preparation for FGKASLR like supporting more
#        than 64K section headers in the relocs tool, correct ORC lookup table
#        size to cover the whole kernel .text and other adjustments.

#       selftests/x86/iopl: Adjust to the faked iopl CLI/STI usage
#       vmlinux.lds.h: Have ORC lookup cover entire _etext - _stext
#       x86/boot/compressed: Avoid duplicate malloc() implementations
#       x86/boot: Allow a "silent" kaslr random byte fetch
#       x86/tools/relocs: Support >64K section headers
#       x86/sev: Make the #VC exception stacks part of the default stacks storage
#       x86: Increase exception stack sizes
#       x86/mm/64: Improve stack overflow warnings
