089b772f98 Remove __ASSUME_PPOLL. 
With current kernel version requirements, the ppoll Linux syscall can
be assumed to be present on all architectures; this patch removes the
__ASSUME_PPOLL macro and conditionals on it and on whether __NR_ppoll
is defined.  (Note that the same can't yet be done for pselect,
because MicroBlaze only wired that up in the syscall table in 3.15.)

Tested for x86_64 and x86 that installed stripped shared libraries are
unchanged by the patch.

	* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_PPOLL):
	Remove macro.
	* sysdeps/unix/sysv/linux/ppoll.c: Do not include
	<kernel-features.h>.
	[__NR_ppoll]: Make code unconditional.
	[!__ASSUME_PPOLL]: Remove conditional code.

c6bb095eb5 nptl: Rewrite cancellation macros 
This patch changes the way cancellation entrypoints are defined to
instead call the macro SYSCALL_CANCEL.  An usual cnacellation definition
is defined as:

  if (SINGLE_THREAD_P)
    return INLINE_SYSCALL (syscall, NARGS, args...)

  int oldtype = LIBC_CANCEL_ASYNC ();

  return INLINE_SYSCALL (syscall, NARGS, args...)

  LIBC_CANCEL_RESET (oldtype);

And it is rewrited as just:

  SYSCALL_CANCEL (syscall, args...)

The idea is to remove LIBC_CANCEL_ASYNC/LIBC_CANCEL_RESET explicit
usage.

Tested on i386, x86_64, powerpc32, powerpc64le, arm, and aarch64.

	* sysdeps/unix/sysdep.h [SYSCALL_CANCEL]: New macro: define
	cancellable syscalls.
