From 52480ee5206a3fe3a61b5529ce063202c60b8b27 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Fri, 12 Oct 2007 16:11:50 +0200 Subject: [PATCH] [S390] s390: use PAGE_SIZE in vmlinux.lds Replace the hardcoded 4096 value with the PAGE_SIZE macro. Converted a few decimal numbers to readable hex numbers. Use of PAGE_SIZE required a small change to page.h to allow PAGE_SIZE to be used from assembler/linker scripts.
