From e78256b8f3e2850ad55c2d69e1429e6c2607afd3 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Sun, 26 Feb 2006 04:18:37 +0100 Subject: [PATCH] x86-64/i386: Use common X86_PM_TIMER option and make it EMBEDDED This makes x86-64 use the common X86_PM_TIMER Kconfig entry in drivers/acpi And since PM timer is needed for correct timing on a lot of systems now (e.g. AMD dual cores) and we often get bug reports from people who forgot to set it make it depend on CONFIG_EMBEDDED. x86-64 had this change before and it's a good thing. I also fixed the description slightly to make this more clear.
