[PATCH] vmalloc : optimization, cleanup, bugfixes
This patch does three things
1) reorder 'struct vm_struct' to speedup lookups on CPUS with small cache
lines. The fields 'next,addr,size' should be now in the same cache line, to
speedup lookups.
2) One minor cleanup in __get_vm_area_node()
3) Bugfixes in vmalloc_user() and vmalloc_32_user()
NULL returns from __vmalloc() and __find_vm_area() were not tested.
Hmm, so they weren't. As far as testing the return of __find_vm_area,
you can just turn that into a BUG_ON(!area), because at that point,
we've established that the vmalloc succeeded.
