From 4db2ce0199f04b6e99999f22e28ef9a0ae5f0d2f Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 14 Sep 2005 21:47:01 -0700 Subject: [LIB]: Consolidate _atomic_dec_and_lock() Several implementations were essentialy a common piece of C code using the cmpxchg() macro. Put the implementation in one spot that everyone can share, and convert sparc64 over to using this. Alpha is the lone arch-specific implementation, which codes up a special fast path for the common case in order to avoid GP reloading which a pure C version would require. Signed-off-by: David S.
