From: Rene Herman Date: Mon, 11 Aug 2008 15:44:57 +0000 (+0200) Subject: x86, debug: tone down arch/x86/kernel/mpparse.c debugging printk X-Git-Tag: v2.6.27-rc3~51^2~6 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=eeb0d7d113895556db473ff1e638803d7d49bff9;p=linux-2.6-omap-h63xx.git x86, debug: tone down arch/x86/kernel/mpparse.c debugging printk commit 11a62a056093a7f25f1595fbd8bd5f93559572b6 turns some formerly nopped debugging printks in arch/x86/kernel/mppparse.c into regular ones. The one at the top of smp_scan_config() in particular also prints on !CONFIG_SMP/CONFIG_X86_LOCAL_APIC kernels and UP machines without anything resembling MP tables which makes their lowly UP owners wonder... Turn the former Dprintk()s into apic_printk()s instead meaning that their printing is dependent on passing the apic=verbose (or =debug) command line param. On 32-bit, "apic" is a __setup() param which isn't early enough for this code and therefore needs a followup changing it into an early_param(). On 64-bit, it already is.
