x86: cacheline_align tss_struct
The manual padding to align on cacheline size only worked in 32 bit
In 64 bit the structure was not aligned and contained wasted space.
use the compiler ____cachline_aligned to save space & properly align
this structure.
x86_64_default size goes from 9136 -> 8960
x86_64_AMD size goes from 9136 -> 8896
built & running on 2.6.26-rc8.
