Subject[PATCH v2 3/3] x86/kprobes: Remove unneeded arch_within_kprobe_blacklist from x86
Date
Remove x86 specific arch_within_kprobe_blacklist().

Since we have already added all blacklisted symbols to
kprobe blacklist by arch_populate_kprobe_blacklist(),
we don't need arch_within_kprobe_blacklist() on x86
anymore.
