    [PATCH] Add AMD K8 support to 2.5.53. · 8b3c4cbf
    Andi Kleen authored
    Add support for the AMD Opteron/Athlon64/Hammer/K8 line to the 32bit
    kernel.
    
    Mostly just reusing Athlon code with some changed CPU model checks.
    The Hammer has model number 15.
    
    I also fixed rmb()/mb() to use the SSE2 mfence/lfence instructions
    on P4 and Hammer. They are somewhat cheaper than the locked cycle.
