Commit b507146b authored by Linus Torvalds's avatar Linus Torvalds

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

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

   - bug in ahash SG list walking that may lead to crashes

   - resource leak in qat

   - missing RSA dependency that causes it to fail"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: rsa - select crypto mgr dependency
  crypto: hash - Fix page length clamping in hash walk
  crypto: qat - fix adf_ctl_drv.c:undefined reference to adf_init_pf_wq
  crypto: qat - fix invalid pf2vf_resp_wq logic
