The patch titled
fix x86_64 splat
has been removed from the -mm tree. Its filename was
fix-x86_64-splat.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: fix x86_64 splat
From: "Vegard Nossum" <vegard.nossum@xxxxxxxxx>
I have attached two patches. The sched one fixes Andrew's boot
problem. The x86 one is untested, but I believe it is better to BUG
than silently corrupt some arbitrary memory. (Then the callers can be
found easily and fixed at least.)
