Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal

Pull signal/compat fixes from Al Viro:
 "Fixes for several regressions introduced in the last signal.git pile,
  along with fixing bugs in truncate and ftruncate compat (on just about
  anything biarch at least one of those two had been done wrong)."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal:
  compat: restore timerfd settime and gettime compat syscalls
  [regression] braino in "sparc: convert to ksignal"
  fix compat truncate/ftruncate
  switch lseek to COMPAT_SYSCALL_DEFINE
  lseek() and truncate() on sparc really need sign extension
