CPUID bit for RDPID. It's not EBX of Fn0000_0007 but ECX, right?

E.36 "Function 7h - Structured Extended Feature Identifiers in the APM (Doc No. 24594 Rev. 3.3, page 600), RDPID bit is in "EBX".

I think it's  not correct. The correct register is ECX. Table 3.1 in page 74, RDPID description in page 297, Table D-1 in page 591 and real CPU say so. It would be good to fix E. 36's table.

Thanks in advance.
