[PATCH] Convert HPPA to use <bits/fcntl-linux.h> (includes patchto <bits/fcntl-linux.h>


Here's an untested patch to use <bits/fcntl-linux.h> on HPPA. I
noticed that the header did not yet use the updated value of O_SYNC,
so synced this with current Linux kernel headers. Also, HPPA seems to
be the only architecture that defines O_RSYNC, so I had to adjust
<bits/fcntl-linux.h> to allow that.

Ok to commit?

2012-10-20  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/sysv/linux/bits/fcntl-linux.h (O_RSYNC): Define to
	__O_RSYNC if it exists.

	For ports/ChangeLog.hppa:
	* sysdeps/unix/sysv/linux/hppa/bits/fcntl.h: Remove all
	definitions and declarations that are provided by
	<bits/fcntl-linux.h> and include <bits/fcntl-linux.h>.
	(O_SYNC): Sync with Linux kernel headers.
