[PATCH] x86_64: Inclusion of ScaleMP vSMP architecture patches - vsmp_align
vSMP specific alignment patch to 1. Define INTERNODE_CACHE_SHIFT for vSMP 2. Use this for alignment of critical structures 3. Use INTERNODE_CACHE_SHIFT for ARCH_MIN_TASKALIGN, and let the slab align task_struct allocations to the internode cacheline size 4. Introduce and use ARCH_MIN_MMSTRUCT_ALIGN for mm_struct slab allocations.
