   # HEAD: d54d610243a4508183978871e5faff5502786cd4 x86/boot/sev: Avoid shared GHCB page for early memory acceptance

Miscellaneous x86 fixes:

 - Fix hypercall detection on Xen guests

 - Extend the AMD microcode loader SHA check to Zen5,
   to block loading of any unreleased standalone
   Zen5 microcode patches

 - Add new Intel CPU model number for Bartlett Lake

 - Fix the workaround for AMD erratum 1054

 - Fix buggy early memory acceptance between
   SEV-SNP guests and the EFI stub

 Thanks,

	Ingo
