From fb1d9be5967fff0a3c93b06304fd992e3c438b7f Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sun, 29 May 2011 23:12:51 -0400 Subject: Blackfin: optimize double fault boot checking This moves the double fault data used at boot time into a single struct which can then easily be addressed with indexed loads rather than having to explicitly load multiple addresses.
