Merge tag 'x86-cleanups-2023-02-20' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull miscellaneous x86 cleanups from Thomas Gleixner:
- Correct the common copy and pasted mishandling of kstrtobool() in the
strict_sas_size() setup function
- Make recalibrate_cpu_khz() an GPL only export
- Check TSC feature before doing anything else which avoids pointless
code execution if TSC is not available
- Remove or fixup stale and misleading comments
- Remove unused or pointelessly duplicated variables
- Spelling and typo fixes
