Description Rebecca Cran 2021-05-10 09:13:46 UTC 
c:\users\administrator\src\edk2\UefiCpuPkg\Library\MpInitLib\MpLib.c(1268)
: error C2220: warning treated as error - no 'object' file generated
c:\users\administrator\src\edk2\UefiCpuPkg\Library\MpInitLib\MpLib.c(1268)
: warning C4306: 'type cast' : conversion from 'int' to
'SEV_ES_AP_JMP_FAR *' of greater size

"I think the compiler is justified to complain here:

7b7508ad784d1 (Tom Lendacky     2020-08-12 15:21:42 -0500 1268)   JmpFar = (SEV_ES_AP_JMP_FAR *) FixedPcdGet32 (PcdSevEsWorkAreaBase);

The proper way to spell such casts is with (UINTN) in the middle."
