From 94fda49a948a5999699359313a2f857f9d11ff19 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Mon, 23 May 2011 11:38:19 +0200 Subject: [PATCH] Revert "microblaze_mmu_v2: Update signal returning address" This reverts commit 8b28626a6b1522b39f75d0bf80d5dec23c931f5a. Offset -8 is wrong because when it is applied then one instruction before brki r14, 8 is called again when we return. Offset -4 is correct and brki instruction is called again. This change came from ancient MMU kernel.
