Subject: [GIT PULL] x86/apic for 6.6-rc1
Hi Linus,
Please pull some x86/apic changes for 6.6-rc1. This includes a very
thorough rework of the 'struct apic' handlers. Quite a variety of
them popped up over the years, especially in the 32-bit days when odd
apics were much more in vogue.
The end result speaks for itself, which is a removal of a ton of code
and static calls to replace indirect calls.
If there's any breakage here, it's likely to be around the 32-bit
museum pieces that get light to no testing these days.
There is an oddity in the authorship/SoB chains I wanted to point out.
When sticking this series on top of the x86/apic pile, I managed to
replace Thomas's "Author:" with mine for a pair of patches:
28b8235238fa ("x86/apic: Wrap IPI calls into helper functions")
670c04add6e1 ("x86/apic: Nuke ack_APIC_irq()")
This was noticed after sitting in the public tree for a week or two
and I figured you'd rather have slightly wonky authorship than
something that looked like a fresh rebase close to the merge window.
