From e5093ff05d36c64e8f36a9ddb26358256dc133ea Mon Sep 17 00:00:00 2001 From: Srinivasa Ds Date: Tue, 8 Jul 2008 00:22:27 +1000 Subject: [PATCH] powerpc: Implement task_pt_regs() accessor The task_pt_regs() macro allows access to the pt_regs of a given task. This macro is not currently defined for the powerpc architecture, but we need it for some upcoming utrace additions.
