Subject: [PATCH 0/2] arm64: entry: Move ct_user_exit calls earlier
Date: Thu, 1 Aug 2019 16:41:48 +0100 [thread overview]
Message-ID: <20190801154150.195959-1-james.morse@arm.com> (raw)
Hi,
Masami's kprobes series adds a bunch of warnings to do_debug_exception().
When booted with nohz_full and lockdep, these things go off. This is
because the entry code is calling some of the C handlers before
ct_user_exit.
Patch 2 is for consistency, it doesn't look like anything minds
this today.
Thanks,
James Morse (2):
arm64: entry: Move ct_user_exit before any user of RCU
arm64: entry: Move ct_user_exit before we can take another exception
