Subject: [PATCH 4/7] context_tracking: Add stub context_tracking_is_enabled

From: Rik van Riel <riel@...hat.com>

With code elsewhere doing something conditional on whether or not
context tracking is enabled, we want a stub function that tells us
context tracking is not enabled, when CONFIG_CONTEXT_TRACKING is
not set.
