From ee7a76da1ef5e3e5e0e54e84319e435ea25c267c Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Tue, 18 Sep 2007 17:22:59 +1000 Subject: [POWERPC] Size swapper_pg_dir correctly David Gibson pointed out that swapper_pg_dir actually need to be PGD_TABLE_SIZE bytes long not PAGE_SIZE. This actually saves 64k in the bss for a kernel ppc64_defconfig built with CONFIG_PPC_64K_PAGES.
