Sharing of bits/fcntl.h on Linux (SPARC, x86)


Here's a revised patch for a shared bits/fcntl.h on Linux with the
common file and the changes for SPARC and x86. I've tested on x86-64
and x86 but not on SPARC.

Compared to the previous patch, I've fixed a couple of typos and
changed the file names so that bits/fcntl.h stays as is and includes
the generic bits/fcntl-linux.h. Thus every architecture can define
remove all "duplicates" from bits/fcntl.h and include
<bits/fcntl-linux.h>.

I've pushed a personal git branch called aj/shared-linux-fcntl with my
changes. The diffstat shows nicely the savings,

Andreas

 create mode 100644 sysdeps/unix/sysv/linux/bits/fcntl-linux.h


2012-10-17  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/sysv/linux/bits/fcntl-linux.h: New file, contains
	generic values for Linux.

	* sysdeps/unix/sysv/linux/x86/bits/fcntl.h: Remove all definitions
	and declarations that are provided by <bits/fcntl-linux.h> and
	include <bits/fcntl-linux.h>.
	* sysdeps/unix/sysv/linux/sparc/bits/fcntl.h: Likewise.
