From 280e109992831ee16a0f74ae887c08fb26c021f1 Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Thu, 21 May 2015 12:13:02 +0530 Subject: [PATCH] powerpc/kernel: Remove the unused extern dscr_default The process context switch code no longer uses dscr_default variable from the sysfs.c file. The variable became unused when we started storing the CPU specific DSCR value in the PACA structure instead. This patch just removes this extern declaration. It was originally added by the following commit.
