From 731f1872f4e8a0f1eabd49c3548207e79a421202 Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Tue, 20 Jan 2009 10:37:39 +0100 Subject: x86: mtrr fix debug boot parameter while looking at: http://bugzilla.kernel.org/show_bug.cgi?id=11541 I realized that the mtrr.show param cannot work, because the code is processed much too early. This patch: - Declares mtrr.show as early_param - Stays consistent with the previous param (which I doubt that it ever worked), so mtrr.show=1 would still work - Declares mtrr_show as initdata Signed-off-by: Thomas Renninger Acked-by: Jan Beulich Signed-off-by: Ingo Molnar --- arch/x86/kernel/cpu/mtrr/generic.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'arch/x86') diff --git a/arch/x86/kernel/cpu/mtrr/generic.c b/arch/x86/kernel/cpu/mtrr/generic.c index b59ddcc88cd8..0c0a455fe95c 100644 --- a/arch/x86/kernel/cpu/mtrr/generic.c +++ b/arch/x86/kernel/cpu/mtrr/generic.c @@ -33,11 +33,13 @@ u64 mtrr_tom2; struct mtrr_state_type mtrr_state = {}; EXPORT_SYMBOL_GPL(mtrr_state); -#undef MODULE_PARAM_PREFIX -#define MODULE_PARAM_PREFIX "mtrr." - -static int mtrr_show; -module_param_named(show, mtrr_show, bool, 0); +static int __initdata mtrr_show; +static int __init mtrr_debug(char *opt) +{ + mtrr_show = 1; + return 0; +} +early_param("mtrr.show", mtrr_debug); /* * Returns the effective MTRR type for the region -- cgit v1.2.3
