Subject: Split part of sys/timerfd.h into bits/timerfd.h
Similar to the patches for other headers, here's the patch splitting
architecture-dependent flags from sys/timerfd.h into bits/timerfd.h.

2012-02-16  Joseph Myers  <joseph@codesourcery.com>

	* sysdeps/unix/sysv/linux/bits/timerfd.h: New file.
	* sysdeps/unix/sysv/linux/sparc/bits/timerfd.h: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sys/timerfd.h: Remove.
	* sysdeps/unix/sysv/linux/sys/timerfd.h: Get flags from
	<bits/timerfd.h>.
	(TFD_CLOEXEC, TFD_NONBLOCK): Don't define here.
	* sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Add
	bits/timerfd.h.
