[PATCH 00/19] sched-numa rewrite

From: Peter Zijlstra
Date: Tue Jul 31 2012 - 15:44:49 EST


Hi all,

After having had a talk with Rik about all this NUMA nonsense where he proposed
the scheme implemented in the next to last patch, I came up with a related
means of doing the home-node selection.

I've also switched to (ab)using PROT_NONE for driving the migration faults.

These patches go on top of tip/master with origin/master (Linus' tree) merged in.

Since the posting of last week (which was private due to operator error and not
intention) Ingo dropped all the previous patches from tip and I did a complete
rebase of the series, making all the back and forth of old and new stuff go away.
