Kernel prepatch 6.12-rc2

Linus has released 6.12-rc2 for testing.

Anyway, this isn't one of the small rc2's. But looking athistorical trends, being a bigger rc2 isn't _that_ unusual, andnothing in here looks all that odd. Yes, the diffstat may look abit unusual, in that we had a global header renaming(asm/unaligned.h -> linux/unaligned.h) and we had a couple ofreverts that stand out as spikes in the stats, but everything elselooks nice and small.
