[PATCH v3 0/7] x86: remaining -Wmissing-prototype warning fixes

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

This is almost the same as before, and should let us turn
on -Wmissing-prototypes by default. I'm still unsure whether
we need to do this per architecture as some other ones still
produce a lot of warnings, or we just enabled it for everyone
and let arch maintainers deal with it now that the major
ones (x86, arm64, arm, powerpc, riscv, s390) are clean.

Changes compared to v2:
 - add amd_check_microcode() patch to the series. I had
   sent that separately as this was a regression in 6.5-rc

 - rework comment for __div64_32

 - split paravirt patch into two patches and rewrite
   the native_pv_lock_init() one as requested by Boris
