    SubjectRe: O(1) scheduler "complex" macros

    the best solution might be to just lock the 'next' task - this needs a new
    per-task irq-safe spinlock, to avoid deadlocks. This way whenever a task
    is in the middle of a context-switch it cannot be scheduled on another

    in fact this solution simplifies things - only two per-arch macros are
    needed. I've done this in my current 2.5.25 tree:

    check out the sparc64 changes for the 'complex' locking scenario - it's
    untested, please give it a go on ia64, does that solve your problems? x86
    is tested and works just fine.
