To avoid data overflow, limit the max value written to EBX[23:16] to

It's bett
The legacy topology enumerated by CPUID.1.EBX[23:16] is defined in SDM
Vol2:
Bits 23-16: Maximum number of addressable IDs for logical processors in
this physical package.
To avoid data overflow, limit the max value written to EBX[23:16] to
255.
