Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6
Pull crypto fixes from Herbert Xu: - vmalloc stack regression in CCM - Build problem in CRC32 on ARM - Memory leak in cavium - Missing Kconfig dependencies in atmel and mediatek - XTS Regression on some platforms (s390 and ppc) - Memory overrun in CCM test vector * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: vmx - Use skcipher for xts fallback crypto: vmx - Use skcipher for cbc fallback crypto: testmgr - Pad aes_ccm_enc_tv_template vector crypto: arm/crc32 - add build time test for CRC instruction support crypto: arm/crc32 - fix build error with outdated binutils crypto: ccm - move cbcmac input off the stack crypto: xts - Propagate NEED_FALLBACK bit crypto: api - Add crypto_requires_off helper crypto: atmel - CRYPTO_DEV_MEDIATEK should depend on HAS_DMA crypto: atmel - CRYPTO_DEV_ATMEL_TDES and CRYPTO_DEV_ATMEL_SHA should depend on HAS_DMA crypto: cavium - fix leak on curr if curr->head fails to be allocated crypto: cavium - Fix couple of static checker errors
