Cover letter [PATCH v3 0/5] x86/cpu: Refactor identify_cpu()
Refactor identify_cpu() machinery on x86 and then implement a fix for a bug when cpu capabilities are temporarily cleared within an interruptable window. For more details and discussion see the relevant bug report [1] and patch #5 ("x86/cpu: Don't transiently clear the boot CPU's capabilities").

v2->v3:
* Commit message edits on patches #1, #2, #5
v2: https://lore.kernel.org/bpf/[email protected]/
v1->v2:
* Rewrite commit messages to fit more conventional structure (Boris)
* Drop identify_cpu_32() helper, it's unnecessary (Boris)
* New patch (#2): now early_identify_cpu() resets boot_cpu_data through init_cpu_info() as well
* The boot CPU reset is now skipped on 32-bit too (sashiko)
