Pull x86 fixes from Ingo Molnar:
"Miscellaneous topology parsing fixes:
- Fix topology parsing regression on older CPUs in the new AMD/Hygon
parser
- Fix boot crash on odd Intel Quark and similar CPUs that do not fill
out cpuinfo_x86::x86_clflush_size and zero out
cpuinfo_x86::x86_cache_alignment as a result.
Provide 32 bytes as a general fallback value.
- Fix topology enumeration on certain rare CPUs where the BIOS locks
certain CPUID leaves and the kernel unlocked them late, which broke
with the new topology parsing code. Factor out this unlocking logic
and move it earlier in the parsing sequence"
