Due to timezones, commit: b956575b ("x86/mm: Flush more aggressively in lazy TLB mode") was an outdated patch that well tested and fixed the bug but didn't address Borislav's review comments.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.
