Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu:
"This fixes a duplicate dma_unmap_sg call in omap-des and reentrancy
bugs in the powerpc nx driver which may cause bogus output or worse
memory corruption"
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: nx - Fix reentrancy bugs
crypto: omap-des - Fix unmapping of dma channels
