Re: [PULL] x86 cpumask work

[Cliff Wickman]

From: Cliff Wickman <cpw@xxxxxxx>

A patch on Mar13 2009 introduced a bug. I hope the below 1-line fix can
make the 'urgent' list, and get fixed before that patch moves on.

The Mar13 patch is saved at
http://marc.info/?l=linux-kernel&m=123683186504948&w=2

The allocation of per-cpu uv_flush_tlb_mask's in arch/x86/kernel/tlb_uv.c
changed a variable that should been reset to 0.
