Date: Sun Jun 05 2022 - 05:31:52 EST
Linus,
please pull the latest x86/cleanups branch from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-cleanups-2022-06-05
up to: f7081834b2d5: x86: Fix all occurences of the "the the" typo
A set of small x86 cleanups:
- Remove unused headers in the IDT code
- Kconfig indendation and comment fixes
- Fix all 'the the' typos in one go instead of waiting for bots to fix
one at a time.
Thanks,
tglx
