From e7e847cd5c60d51bf5a50663a191b4e622c5c234 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Thu, 27 Jun 2013 08:20:09 +0300 Subject: CBMEM AMD: Remove references to global high_tables_base MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Prepare for removal of globals high_tables_base and _size by replacing the references with a helper function. Added set_top_of_ram_once() may be called several times, but only the first call (with non-zero argument) takes effect.
