WORK_AREA_GUEST_TYPE is defined in https://github.com/tianocore/edk2/blob/master/OvmfPkg/ResetVector/ResetVector.nasmb#L75 and previously it was cleared in https://github.com/tianocore/edk2/blob/master/OvmfPkg/ResetVector/Ia32/PageTables64.asm#L47. These 2 lines are both surrounded by ARCH_X64.
So in this commit, the clearance of WORK_AREA_GUEST_TYPE in Main.asm is surrounded by ARCH_X64 too.
Brijesh, what's your comments on this change?

Thanks!
