Subject[GIT PULL] x86/core for v5.16

And doing the pull request message now, it looks like I could have
simply used as the <start> point in the invocation of

$ git request-pull [-p] <start> <url> [<end>]

the merged branch. I.e., usually I do:

$ git request-pull master tip x86_core_for_v5.16_rc1

i.e., master up to the tag and doing

$ git request-pull tip/x86/cc tip x86_core_for_v5.16_rc1

where tip/x86/cc is the branch which had to be merged into x86/core,
gives the exact same diffstat etc...

Now, with that out of the way, you can finally please pull the x86/core
updates for 5.16.

Btw, there's a small merge conflict with your tree, resolution at the
end of this mail, courtesy of Ingo.

Thanks!

selftests/x86/iopl: Adjust to the faked iopl CLI/STI usage (2021-10-30 23:18:04 +0200)

----------------------------------------------------------------
- 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.
