Is there anything else needed from me for this patch at this time?

Subject: [edk2-devel] [PATCH v6 0/4] AMD processor MSR_IA32_MISC_ENABLE

[CAUTION: External Email]

AMD processor does not support MSR_IA32_MISC_ENABLE register.  Accessing this 
register on AMD causes an unhandled exception in SmmEntry.nasm and a subsequent 
failure to boot since this is too early in SMM path for the exception handler 
to be loaded.

1. Prepare PcAtChipsetPkg/PcAtChipsetPkg.dsc to move 
StandardSignatureIsAuthenticAMD into UefiCpuLib LibraryClass BaseUefiCpuLib in 
UefiCpuPkg.

2. To distinguish between AMD and other processors, refactor 
StandardSignatureIsAuthenticAMD into BaseUefiCpuLib.  So there is only one copy 
in the source.

3. Skip manipulation of MSR_IA32_MISC_ENABLE register if running on an AMD 
processor.

Tested on AMD X64 hardware.
OvmfIa32 and OvmfIa32X64 on Intel hardware.

v1: Move StandardSignatureIsAuthenticAMD. Handle MSR_IA32_MISC_ENABLE
v2: Incorporate Laszlo's feedback
v3: Typo, not sent
v4: Patch in to add UefiCpuLib to PcAtChipsetPkg.dsc
v5: Patch in to add UefiCpuLib to SourceLevelDebugPkg.dsc
v6: Hopefully reformat patch when sending????

Garrett Kirkendall (4):
  PcAtChipsetPkg: PcAtChipsetPkg.dsc add UefiCpuLib LibraryClass
  SourceLevelDebugPkg: SourceLevelDebugPkg.dsc add UefiCpuLib
    LibraryClass
  UefiCpuPkg: Move StandardSignatureIsAuthenticAMD to BaseUefiCpuLib
  UefiCpuPkg: PiSmmCpuDxeSmm skip MSR_IA32_MISC_ENABLE manipulation on
    AMD
