From aa770aa790f3a5f3ff568388d02aea2ef78773ec Mon Sep 17 00:00:00 2001 From: Robin Getz Date: Mon, 29 Oct 2007 18:14:15 +0800 Subject: [PATCH] Blackfin arch: Fix random crash issue found by Michael. This is fixes a problem where we could jump to the wrong address. By doing a "p0 = reti; jump (p0)". If a different, higher level interrupt came in, just before, rather than returning to the calling function, we would return to a random place in the kernel. This very elegant fix from Bernd grabs the return location off the stack, and places it into P0, so when we do a return, it goes to the correct place.
