    [POWERPC] PS3: Fix bug where the major version part is not compared
    
    Fix the bug that the major version part of the firmware version number
    is ignored in the comparison done by ps3_compare_firmware_version
    because the difference of two 64-bit quantities is returned as an int.

    [POWERPC] spufs: Don't call spu_run_init from spu_reacquire_runnable
    
    This fixes a major bug which was happening when a SPU thread advances
    its execution right after being restored to a SPU.  A potentially
    outdated NPC value was being (re)written to the SPU.
    
    So, spu_run_init, in this case, was either not doing anything relevant,
    or breaking the execution of the SPU thread.
    
    This fixes a common problem of losing a mailbox write when it was done
    to a saved context.

    [POWERPC] spufs: Fix update of mailbox status register during backed wbox write
    
    When a process writes into the inbound spu mailbox (wbox) while the
    context is saved, we accidentally break the contents of the mb_stat_R
    register by clearing other entries of the mailbox status register. This
    can cause the user side to hang.
    
    This change fixes the problem by only altering the appropriate bits
    of the mailbox status register during a backing-store write.

    [POWERPC] spu_manage: fix spu_unit_number for celleb device tree
    
    This fixes a regression introduced with 2.6.23-rc4 after on some
    confusion about the device tree interfaces.
    
    IBM QS21 device trees provide "physical-id", so we changed the code to
    run on that and remain compatible with all IBM machines.
    
    However, the Toshiba Celleb device tree provides the "unit-id" property,
    which was in the Linux code, but never used in this way on IBM hardware.
    
    Legacy device tree used the reg property for the physical id of an spe.
    This patch fixes find_spu_unit_number to look for the spu id in that order.
    The length is checked to avoid misinterpretation in case the attributes
    unit-id or reg do not contain the id.

    [POWERPC] Flush registers to proper task context
    
    When we flush register state for FP, Altivec, or SPE in flush_*_to_thread
    we need to respect the task_struct that the caller has passed to us.
    
    Most cases we are called with current, however sometimes (ptrace) we may
    be passed a different task_struct.
    
    This showed up when using gdbserver debugging a simple program that used
    floating point. When gdb tried to show the FP regs they all showed up as
    0, because the child's FP registers were never properly flushed to memory.
