From ea0364f1bbfed1e3ea711147420875cf338fe77a Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Mon, 12 Apr 2010 22:28:04 -0500 Subject: Move lib_$ARCH directories to arch/$ARCH/lib Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization.
