Message-ID: <152261522745.30503.11022506204837457606.stgit@warthog.procyon.org.uk> Date: Sun, 01 Apr 2018 21:40:27 +0100 From: David Howells <dhowells@...hat.com> To: linux-kernel@...r.kernel.org Subject: [PATCH 02/45] Fix exception_enter() return value Fix the return value of exception_enter() to return CONTEXT_KERNEL rather than 0 when the facility is disabled as the function returns an ctx_state enum rather than a plain integer.
