Re: [edk2-devel] [Patch V2 0/2] Change the usage of input parameter ProcessorNumber in MpInitLibGetProcessorInfo() of MpInitLibUp

[duntan]

Please ignore the V2 patch set and help review the following V3 patch set. 
" [Patch V3 2/2] UefiCpuPkg: Check lower 24 bits of ProcessorNumber"
" [Patch V3 1/2] UefiCpuPkg: set EXTENDED_PROCESSOR_INFORMATION to 0"

There was build error in the v2 patch series and  the error was fixed in V3 patch set.

Thanks,
Dun

Subject: [edk2-devel] [Patch V2 0/2] Change the usage of input parameter ProcessorNumber in MpInitLibGetProcessorInfo() of MpInitLibUp

In the V2 patch set:
In "set EXTENDED_PROCESSOR_INFORMATION to 0", set EXTENDED_PROCESSOR_INFORMATION to 0 in API MpInitLibGetProcessorInfo() of MpInitLibUp. This commit use ZeroMem() to set all fileds in output EFI_PROCESSOR_INFORMATION to 0 before StatusFlag field is reassigned.

In "Check lower 24 bits of ProcessorNumber", use BIT24 instead of CPU_V2_EXTENDED_TOPOLOGY to clearly tell that processor number only occupies the lower 24 bits.
