Pull crypto fixes from Herbert Xu:
 "This fixes the following issues:

   - memory corruption when kmalloc fails in xts/lrw

   - mark some CCP DMA channels as private

   - fix reordering race in padata

   - regression in omap-rng DT description"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
