x86/mm: Tidy up "x86/mm: Flush more aggressively in lazy TLB mode"
Due to timezones, commit:
b956575bed91 ("x86/mm: Flush more aggressively in lazy TLB mode")
was an outdated patch that well tested and fixed the bug but didn't
address Borislav's review comments.
Tidy it up:
- The name "tlb_use_lazy_mode()" was highly confusing. Change it to
"tlb_defer_switch_to_init_mm()", which describes what it actually
means.
- Move the static_branch crap into a helper.
- Improve comments.
Actually removing the debugfs option is in the next patch.
