[PATCH] IA64: kprobe invalidate icache of jump buffer
Kprobe inserts breakpoint instruction in probepoint and then jumps to instruction slot when breakpoint is hit, the instruction slot icache must be consistent with dcache. Here is the patch which invalidates instruction slot icache area. Without this patch, in some machines there will be fault when executing instruction slot where icache content is inconsistent with dcache.
