[0/8] xen: Untangle mm.h

Message

Andrew Cooper March 12, 2025, 5:45 p.m. UTC

This started out trying to fix one little TODO in x86's microcode loader, and
escalated somewhat...

tlb-clock.h is definitely not as clean as it could be, but it's an improvment
over today, and given how long it's taken to get this to compile, I'm not
looking to rewrite everything.

Andrew Cooper (8):
  xen/elfstructs: Include xen/types.h
  xen/livepatch: Fix include hierarchy
  xen: Sort includes
  xen/common: Split tlb-clock.h out of mm.h
  xen/arch: Strip out tlb-clock stubs for non-implementors
  xen/mm: Exclude flushtlb.h from mm.h for PPC and RISC-V
  xen/mm: Exclude flushtlb.h from mm.h for ARM
  xen/mm: Exclude flushtlb.h from mm.h for x86

The other thing to say, I expect randconfig to shake out some things,
and FreeBSD Randconfig already has.

I'll let the piplines run for a bit before accumulating.
