From 442464a50077ff00454ff8d7628cbe1b8eacc034 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 29 Aug 2005 12:46:07 -0700 Subject: [SPARC64]: Make debugging spinlocks usable again. When the spinlock routines were moved out of line into kernel/spinlock.c this made it so that the debugging spinlocks record lock acquisition program counts in the kernel/spinlock.c functions not in their callers. This makes the debugging info kind of useless. So record the correct caller's program counter and now this feature is useful once more. Signed-off-by: David S.
