    [PATCH] Fix ppc64 max_pfn issue · 1172fbd0
    Anton Blanchard authored
    I noticed excessive time in the pid hash functions on a ppc64 box. It
    turns out the pid hash is being sized way too small, eg on a 16GB box:
    
    PID hash table entries: 16 (order 4: 256 bytes)
    
    The reason is that the pid hash init function uses max_pfn before it was
    setup on ppc64. With the following patch things are good again:
    
    PID hash table entries: 4096 (order 12: 65536 bytes)
