Subject: [GIT PULL] x86/alternatives for v6.10-rc1

Hi Linus,

please pull x86/alternatives for v6.10-rc1.

You might encounter an easy peasy merge conflict which you can resolve
by simply zapping alternative_input_2(), i.e., what

8dc8b02d707e ("x86/alternatives: Remove alternative_input_2()")

does.

Thx.

x86/alternatives: Remove alternative_input_2() (2024-05-06 14:30:54 +0200)

----------------------------------------------------------------
- Switch the in-place instruction patching which lead to at least one weird bug
with 32-bit guests, seeing stale instruction bytes, to one working on
a buffer, like the rest of the alternatives code does

- Add a long overdue check to the X86_FEATURE flag modifying functions to warn
when former get changed in a non-compatible way after alternatives have been
patched because those changes will be already wrong

- Other cleanups

----------------------------------------------------------------
Borislav Petkov (AMD) (6):
x86/alternatives: Catch late X86_FEATURE modifiers
x86/alternatives: Use a temporary buffer when optimizing NOPs
x86/alternatives: Get rid of __optimize_nops()
x86/alternatives: Optimize optimize_nops()
x86/alternatives: Sort local vars in apply_alternatives()
x86/alternatives: Remove alternative_input_2()
