Subject: [PATCH] Latest clang is causing build failures because -Werror is
 used

  edk2/MdeModulePkg/Include/Guid/ExtendedFirmwarePerformance.h:78:47:
  error: field Guid within 'FPDT_GUID_EVENT_RECORD' is less aligned than 'EFI_GUID'
  and is usually due to 'FPDT_GUID_EVENT_RECORD' being packed, which can lead to
  unaligned accesses [-Werror,-Wunaligned-access]

This has been reported upstream[1] so until this is resolved, ignore the warnings.
