Basically tip-off the powerpc code, use a 64-bit type and atomic64_t interfaces for the implementation. This gets us off of the by-hand asm code I wrote, which frankly I think probably ruins I-cache hit rates. The idea was the keep the call chains less deep, but anything taking the rw-semaphores probably is also calling other stuff and therefore already has allocated a stack-frame. So no real stack frame savings ever. Ben H. has posted patches to make powerpc use 64-bit too and with some abstractions we can probably use a shared header file somewhere. With suggestions from Sam Ravnborg. Signed-off-by: David S. Miller <davem@davemloft.net>
