[PATCH] i386: Account spinlocks to the caller during profiling for !FP kernels
This ports the algorithm from x86-64 (with improvements) to i386. Previously this only worked for frame pointer enabled kernels. But spinlocks have a very simple stack frame that can be manually analyzed. Do this. Signed-off-by: Andi Kleen <ak@suse.de>
