Subject: [PATCH 08/14] header: nospec.h: provide dummy header file
Date: Sun, 4 Mar 2018 23:57:11 +0100 [thread overview]
Message-ID: <20180304225717.20890-9-hauke@hauke-m.de> (raw)
In-Reply-To: <20180304225717.20890-1-hauke@hauke-m.de>
Older kernel versions do not have the include linux/nospec.h with the
function array_index_nospec, provide a dummy implementation for these
kernel versions and forward the call the the real version for capable
kernel versions.
