Ok, looks mostly good to me and I've applied the first 6 patches to tip:x86/mm
and
will push them out if everything tests out fine.
Regarding patch #7: could you please split the last patch into two, and rebase
the
wp_works_ok removal on the very latest tip:x86/mm tree? There's some pending
changes in tip:x86/process that conflict badly, so I've merged it into
tip:x86/mm
for a conflict-free base. That patch is better split in two anyway, as it does
two
only marginally related things.
Thanks,
Ingo
