From 1e1030dccb1084c8a38976d3656aab1d50d762da Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 1 Sep 2009 17:38:32 +0900 Subject: sh: nmi_debug support. This implements support for NMI debugging that was shamelessly copied from the avr32 port. A bit of special magic is needed in the interrupt exception path given that the NMI exception handler is stubbed in to the regular exception handling table despite being reported in INTEVT. So we mangle the lookup and kick off an EXPEVT-style exception dispatch from the INTEVT path for exceptions that do_IRQ() has no chance of handling. As a result, we also drop the evt2irq() conversion from the do_IRQ() path and just do it in assembly.
