Subject: [PATCH] xen: switch to post-init routines in xen mmu.c earlier
Date: Wed, 10 Dec 2014 16:56:03 +0100 [thread overview]
Message-ID: <1418226963-24873-1-git-send-email-jgross@suse.com> (raw)
With the virtual mapped linear p2m list the post-init mmu operations
must be used for setting up the p2m mappings, as in case of
CONFIG_FLATMEM the init routines may trigger BUGs.
