From b8b572e1015f81b4e748417be2629dfe51ab99f9 Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Fri, 1 Aug 2008 15:20:30 +1000 Subject: powerpc: Move include files to arch/powerpc/include/asm from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc.
