Subject: ARM: use high vectors if possible
Date: Mon, 8 Aug 2011 08:46:35 +0200 [thread overview]
Message-ID: <1312786003-14734-1-git-send-email-s.hauer@pengutronix.de> (raw)
Created this series to get high vector support. Using high vectors
at 0xffff0000 allow us to map in a faulting page at 0x0 with which
we can catch NULL pointer dereferences. The other patches are only
some cleanups around exceptions which I came along the way.
