Kernel prepatch 6.2-rc5

Ok, so I thought we were back to normal after the winter holidays
at rc4. Now, a week later, I think I was mistaken - we have fairly
sizable rc5, so I suspect there was still pent up testing and fixes
from people being off.

Anyway, I am expecting to do an rc8 this release regardless, just
because we effectively had a lost week or two in the early rc's, so
a sizable rc5 doesn't really worry me. I do hope we're done with
the release candidates growing, though.
