rwsem: Move duplicate function prototypes to linux/rwsem.h

2011-01-27T11:30:39+00:00

All architecture specific rwsem headers carry the same function
prototypes. Just x86 adds asmregparm, which is an empty define on all
other architectures. S390 has a stale rwsem_downgrade_write()
prototype.

Remove the duplicates and add the prototypes to linux/rwsem.h

rwsem: Unify the duplicate rwsem_is_locked() inlines

2011-01-27T11:30:39+00:00

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.h

2011-01-27T11:30:39+00:00

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

rwsem: Move duplicate struct rwsem declaration to linux/rwsem.h

2011-01-27T11:30:39+00:00

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.

SPIN_LOCK_UNLOCK is deprecated. Use the lockdep capable variant
instead.

alpha: move include/asm-alpha to arch/alpha/include/asm

2008-08-15T16:19:40+00:00

Sam Ravnborg did the build-test that the direct header file move works,
I'm just committing it.

This is a pure move:

	mkdir arch/alpha/include
	git mv include/asm-alpha arch/alpha/include/asm

with no other changes.
