--- Comment #4 from Hongxu Jia <hongxu.jia at windriver.com> ---
I am afraid the fix of your
patch[https://bugzilla.nasm.us/attachment.cgi?id=411647&action=diff] caused
build ovmf failed.

In ovmf
vim UefiCpuPkg/Library/CpuExceptionHandlerLib/X64/ExceptionHandlerAsm.nasm
[snip]
 38 AsmIdtVectorBegin:
 39 %rep  32
 40     db      0x6a        ; push  #VectorNum
 41     db      ($ - AsmIdtVectorBegin) / ((AsmIdtVectorEnd -
AsmIdtVectorBegin) / 32) ; VectorNum
 42     push    rax
 43     mov     rax, ASM_PFX(CommonInterruptEntry)
 44     jmp     rax
 45 %endrep
 46 AsmIdtVectorEnd:
