      Merge branch 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6 · 178e834c
      Linus Torvalds authored 
      Pull crypto fixes from Herbert Xu:
 "This fixes the following issues:

   - oversize stack frames on mn10300 in sha3-generic

   - warning on old compilers in sha3-generic

   - API error in sun4i_ss_prng

   - potential dead-lock in sun4i_ss_prng

   - null-pointer dereference in sha512-mb

   - endless loop when DECO acquire fails in caam

   - kernel oops when hashing empty message in talitos"

* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
  crypto: sun4i_ss_prng - convert lock to _bh in sun4i_ss_prng_generate
  crypto: sun4i_ss_prng - fix return value of sun4i_ss_prng_generate
  crypto: caam - fix endless loop when DECO acquire fails
  crypto: sha3-generic - Use __optimize to support old compilers
  compiler-gcc.h: __nostackprotector needs gcc-4.4 and up
  compiler-gcc.h: Introduce __optimize function attribute
  crypto: sha3-generic - deal with oversize stack frames
  crypto: talitos - fix Kernel Oops on hashing an empty file
  crypto: sha512-mb - initialize pending lengths correctly

      unify {de,}mangle_poll(), get rid of kernel-side POLL... · 7a163b21
      Al Viro authored 
      except, again, POLLFREE and POLL_BUSY_LOOP.

With this, we finally get to the promised end result:

 - POLL{IN,OUT,...} are plain integers and *not* in __poll_t, so any
   stray instances of ->poll() still using those will be caught by
   sparse.

 - eventpoll.c and select.c warning-free wrt __poll_t

 - no more kernel-side definitions of POLL... - userland ones are
   visible through the entire kernel (and used pretty much only for
   mangle/demangle)

 - same behavior as after the first series (i.e. sparc et.al. epoll(2)
   working correctly).

      vfs: do bulk POLL* -> EPOLL* replacement · a9a08845
      Linus Torvalds authored 
      This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.
