Message-Id: <1212552507-15134-1-git-send-email-gcosta@redhat.com> Date: Wed, 4 Jun 2008 01:08:27 -0300 From: Glauber Costa <gcosta@...hat.com> To: linux-kernel@...r.kernel.org Cc: akpm@...ux-foundation.org, tglx@...utronix.de, mingo@...e.hu, Yinghai Lu <yhlu.kernel@...il.com> Subject: [PATCH] Make x86 latest boot with non-discontig boxes Commit 0596152388e234efebce464355186ad9e16c8cb6 broke my box, since it removes completely the call to memory_present() at e820 setup. It seems to be really not needed with discontig memory, but with flat and sparse, I get an early crash. The proposed patch moves the call memory_present() to setup_memory, the one present in setup_32.c.
