Seeing this error on SPARC while compiling qrwlock.c.

   CC      kernel/locking/qrwlock.o
In file included from ./include/asm-generic/qrwlock_types.h:5,

Re-arrange the includes in qrwlock_types.h and also include spinlock.h
in qrwlock.c to fix it. This should also help other architectures when
queued rwlock is enabled.

I think you can simply remove the:

#ifndef __LINUX_SPINLOCK_TYPES_H
# error "please don't include this file directly"
#endif

stanza from the sparc header file instead.  Other architectures
don't use this guard.

Sure. I can remove this for SPARC.  Will make this as a separate patch.
But, there are still some architectures use this gaurd.

I think we need  still need this patch as it re-arrages headers 
properly. Will send  v2 series soon.
