    SubjectRe: [PATCH] x86-32: Allocate irq stacks seperate from percpu area

    Ok, so I definitely want this (although it sounds like it would be
    good to do the allocation numa-aware - possibly a separate issue).

    However, I also want to remove all the crap that got added for the
    multi-page percpu support. It was ugly, and apparently never really
    worked. All the PER_CPU_MULTIPAGE_ALIGNED crud just needs to go away.

    Ingo, can you take care of this all, or should I just take the patch
    and remove the multipage stuff manually?
