From 584224e4095d8abcf2bef38efacc291be9a44c20 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 9 Nov 2005 13:04:06 +1100 Subject: [PATCH] powerpc: Merge current.h This patch merges current.h. This is a one-big-ifdef merge, but both versions are so tiny, I think we can live with it. While we're at it, we get rid of the fairly pointless redirection through get_current() in the ppc64 version. Built and booted on POWER5 LPAR (ARCH=powerpc & ARCH=ppc64). Built for 32-bit pmac (ARCH=powerpc & ARCH=ppc).
