Subject: [PATCH 0/2] arm64: some symbols blacklisted for kprobing

Functions which are called from do_debug_execptions and all entry routines
must not allow to insert kprobe in it, otherwise we may witness a system hang.

This patch set blacklist such symbols.

Patches should be applied on top of arm64 kprobe patches [1].
