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

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.

All rwsem implementations include the same headers. Include them from
include/linux/rwsem.h

SPIN_LOCK_UNLOCK is deprecated. Use the lockdep capable variant
instead.

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.
