This patch in the series is really more of a convenience than anything 
else since it doesn't change anything functionally.  I had to modify the 
lowmemorykiller later because there's a potential for a NULL pointer from 
dereferencing p->mm without holding task_lock(p) and also because I moved 
oomkilladj from struct task_struct to struct mm_struct.

The entire patchset is really based on the move of p->oomkilladj since it 
allows us to prevent an oom killer livelock when killing a task that 
shares memory with an OOM_DISABLE task.  That change obviously has to go 
through Andrew but lowmemorykiller.c must be also be changed accordingly.

I'd be fine with dropping my lowmemorykiller changes if they'd like to fix 
this up themselves.  Otherwise, I need to know the path to which these get 
into the kernel.
