    Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal · 54d46ea9
    Linus Torvalds authored
    Pull signal handling cleanups from Al Viro:
     "sigaltstack infrastructure + conversion for x86, alpha and um,
      COMPAT_SYSCALL_DEFINE infrastructure.
    
      Note that there are several conflicts between "unify
      SS_ONSTACK/SS_DISABLE definitions" and UAPI patches in mainline;
      resolution is trivial - just remove definitions of SS_ONSTACK and
      SS_DISABLED from arch/*/uapi/asm/signal.h; they are all identical and
      include/uapi/linux/signal.h contains the unified variant."
    
    Fixed up conflicts as per Al.
    
    * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal:
      alpha: switch to generic sigaltstack
      new helpers: __save_altstack/__compat_save_altstack, switch x86 and um to those
      generic compat_sys_sigaltstack()
      introduce generic sys_sigaltstack(), switch x86 and um to it
      new helper: compat_user_stack_pointer()
      new helper: restore_altstack()
      unify SS_ONSTACK/SS_DISABLE definitions
      new helper: current_user_stack_pointer()
      missing user_stack_pointer() instances
      Bury the conditionals from kernel_thread/kernel_execve series
      COMPAT_SYSCALL_DEFINE: infrastructure
