I don't know which rewrite you mean. 

If you mean those patches by Ihor:

2711d67bc3a7 x86/cpu: Don't transiently clear the boot CPU's capabilities
db349783ca7a x86/cpu: Move 32-bit SEP setup into identify_cpu()
ad86fe2134cc x86/cpu: Inline generic_identify() into identify_cpu()
7a762b51a149 x86/cpu: Initialize boot CPU cpuinfo defaults early
54a2882ab9f7 x86/cpu: Factor init_cpu_info() out of identify_cpu()

they're in tip queued for 7.4. So not mainline yet.

You can test current tip/master if you mean them.

HTH.
