With all the problems that this, and the 5.15.y and 5.10.y trees are
having right now, I'm going to postpone this whole set of -rc releases
and get to them next week, when all of the needed fixup patches have hit
Linus's tree.

Sorry for the delay all, and thank you to everyone for all of the
testing.  The problems are purely due to the fact that we were forced to
do this type of work "in private" with very limited ability for testing
by the normal larger kernel community like we rely on.  We don't have
fancy or huge private testing labs where we can do all of this work as
we are an open source project, and we rely on open testing in public.

So thanks all for your understanding with the delay.  If you _really_
need protection from RETBLEED, you can grab these patches now, as maybe
the corner cases we have hit so far don't affect you.  Otherwise they
should be ready next week, and I'll do a whole new round of -rc1 with
them.

I think I know what this is and I am just testing a fix. This is due to
FASTOP_SIZE not taking into consideration the size of the return thunk jump.

Seems others are hitting this too:
	https://lore.kernel.org/r/CAMGffEm9y0wnn8LNS9Qo3obPhs0GD5iJZ0WejFzC4baGPDsYTw@mail.gmail.com

Does this also happen right now on Linus's tree?

Warning, but does everything still work?

And again, still on Linus's tree?

Ick, I'll wait for that to get synced in Linus's tree.

Results from Linaro’s test farm.
Regressions on x86_64 (and still validating results)

Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>

1) kernel panic on x86_64 while running kvm-unit-tests.
   - APIC base relocation is unsupported by KVM
2) qemu_x86_64 boot warning
   - WARNING: CPU: 0 PID: 0 at arch/x86/kernel/alternative.c:558
apply_returns+0x19c/0x1d0

3) New warnings noticed while building perf
   - Warning: Kernel ABI header at
'tools/arch/x86/include/asm/disabled-features.h' differs from latest
version at 'arch/x86/include/asm/disabled-features.h'

1. kernel panic on x86_64
