Merge tag 'x86-apic-2024-03-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 APIC fixup from Dave Hansen: "Revert VERW fixed addressing patch. The reverted commit is not x86/apic material and was cruft left over from a merge. I believe the sequence of events went something like this: - The commit in question was added to x86/urgent - x86/urgent was merged into x86/apic to resolve a conflict - The commit was zapped from x86/urgent, but *not* from x86/apic - x86/apic got pullled (yesterday) I think we need to be a bit more vigilant when zapping things to make sure none of the other branches are depending on the zapped material" * tag 'x86-apic-2024-03-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: Revert "x86/bugs: Use fixed addressing for VERW operand"
