From f91fab5eeab9d97123e29876b1d61dc80b31c6de Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Thu, 28 May 2015 10:10:47 +0100 Subject: [PATCH] xen/arm: traps: Print a message in debug build when a guest dabt is not handled This is useful for debugging low level kernel before the guest as setup the vector table. Note that the value of the IPA is only here for reference and may not always be valid if the error came from a stage 1 table translation walk.
