Add add kmalloc_align() for alignment requirement.
Almost no behavior changed nor overhead added.

Lai Jiangshan (6):
  kenrel.h: add ALIGN_OF_LAST_BIT()
  slub: add kmalloc_align()
  slab: add kmalloc_align()
  don't couple the header size with the alignment
  slob: add kmalloc_align()
  workqueue: use kmalloc_align() instead of hacking
