    Percpu on i386 hasn't been a point of discussion. It works fine, and
    has been working fine for a long time. The same mechanism would work
    fine on x86-64. Its only "issue" is that it doesn't support the broken
    gcc abi for stack-protector.

    The problem is all zero-based percpu on x86-64.
