Richard Kennedy 33166b1ffc shrink struct pid by removing padding on 64 bit builds 
When struct pid is built on a 64 bit platform gcc has to insert padding to
maintain the correct alignment, by simply reordering its members the
memory usage shrinks from 88 bytes to 80.

I've successfully run with this patch on my desktop AMD64 machine.

There are no significant kernel size changes to a default config.X86_64
on the latest git v2.6.26-rc1
