   # HEAD: a1e2b8b36820d8c91275f207e77e91645b7c6836 x86/mm: Drop the 4 MB restriction on minimal NUMA node memory size

x86 MM handling code changes for v6.7:

 - Add new NX-stack self-test
 - Improve NUMA partial-CFMWS handling
 - Fix #VC handler bugs resulting in SEV-SNP boot failures
 - Drop the 4MB memory size restriction on minimal NUMA nodes
 - Reorganize headers a bit, in preparation to header dependency reduction efforts
 - Misc cleanups & fixes

 Thanks,

	Ingo
