From 4da487eae8858dc132d60b7ffb0015e9c96b0df6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Thu, 19 Mar 2015 06:58:15 +0200 Subject: CBMEM: Add LATE_CBMEM_INIT guards MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Our target is to get rid of backup_top_of_ram() and get_top_of_ram() entirely so only declare these with LATE_CBMEM_INIT=y.
