Subject: [PATCH 0/2] arm64: some symbols blacklisted for kprobing
Date: Mon, 6 Jul 2015 10:33:20 +0530 [thread overview]
Message-ID: <cover.1436158027.git.panand@redhat.com> (raw)
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].
