* rwsem: Unify the duplicate rwsem_is_locked() inlinesThomas Gleixner2011-01-278-40/+0
| | | | | | | | | | | | | | | | | | | | Instead of having the same implementation in each architecture, move it to linux/rwsem.h and remove the duplicates. It's unlikely that an arch will ever implement something different, but we can deal with that when it happens.

* rwsem: Move duplicate init macros and functions to linux/rwsem.hThomas Gleixner2011-01-278-184/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | The rwsem initializers and related macros and functions are mostly the same. Some of them lack the lockdep initializer, but having it in place does not matter for architectures which do not support lockdep. powerpc, sparc, x86: No functional change sh, s390: Removes the duplicate init_rwsem (inline and #define) alpha, ia64, xtensa: Use the lockdep capable init function in lib/rwsem.c which is just uninlining the init function for the LOCKDEP=n case Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: David Howells <dhowells@redhat.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Matt Turner <mattst88@gmail.com> Acked-by: Tony Luck <tony.luck@intel.com> Acked-by: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Paul Mundt <lethal@linux-sh.org> Acked-by: David Miller <davem@davemloft.net> Cc: Chris Zankel <chris@zankel.net> LKML-Reference: <20110126195833.771812729@linutronix.de>
* rwsem: Move duplicate struct rwsem declaration to linux/rwsem.hThomas Gleixner2011-01-278-77/+3
| | | | | | | | | | | | | | | | | | | | | The difference between these declarations is the data type of the count member and the lack of lockdep in some architectures/ long is equivivalent to signed long and the #ifdef guarded dep_map member does not hurt anyone.
