Merge tag 'x86-misc-2021-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull misc x86 updates from Thomas Gleixner:
"A set of updates for the x86 reboot code:
- Limit the Dell Optiplex 990 quirk to early BIOS versions to avoid
the full 'power cycle' alike reboot which is required for the buggy
BIOSes.
- Update documentation for the reboot=pci command line option and
document how DMI platform quirks can be overridden"
