2008-07-08x86: nmi_watchdog - introduce nmi_watchdog_active() helperCyrill Gorcunov

2008-07-08x86: nmi_watchdog - use NMI_NONE by defaultCyrill Gorcunov
There is no need to keep NMI_DISABLED definition and use it for nmi_watchdog by default. Here is the point why: - IO-APIC and APIC chips are programmed for nmi_watchdog support at very early stage of kernel booting and not having nmi_watchdog specified as boot option lead only to nmi_watchdog becomes to NMI_NONE anyway - enable nmi_watchdog thru /proc/sys/kernel/nmi if it was not specified at boot is not possible too (even having this sysfs entry) Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Cc: macro@linux-mips.org Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-07-08x86: NMI watchdog: Downgrade helperMaciej W. Rozycki
A downgrade helper for the NMI watchdog to be used in all places where the I/O APIC watchdog may have been requested, but the I/O APIC is found not to be there or meant to be left disabled. This is so that the reconfiguration is cosistent and defined in a single place only. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-06-05x86: nmi - consolidate nmi_watchdog_default for 32bit modeCyrill Gorcunov
64bit mode bootstrap code does set nmi_watchdog to NMI_NONE by default and doing the same on 32bit mode is safe too. Such an action saves us from several #ifdef. Btw, my previous commit commit 19ec673ced067316b9732bc6d1c4ff4052e5f795 Author: Cyrill Gorcunov <gorcunov@gmail.com> Date: Wed May 28 23:00:47 2008 +0400 x86: nmi - fix incorrect NMI watchdog used by default did not fix the problem completely, moreover it introduced additional bug - nmi_watchdog would be set to either NMI_LOCAL_APIC or NMI_IO_APIC _regardless_ to boot option if being enabled thru /proc/sys/kernel/nmi_watchdog. Sorry for that. Fix it too. Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> Cc: mingo@redhat.com Cc: hpa@zytor.com Cc: macro@linux-mips.org Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2008-05-28x86: nmi - fix incorrect NMI watchdog used by defaultCyrill Gorcunov
The commit commit 4b82b277707a39b97271439c475f186f63ec4692 Author: Cyrill Gorcunov <gorcunov@gmail.com> Date: Sat May 24 19:36:35 2008 +0400 set nmi_watchdog to NMI_IO_APIC as by default. This causes hangs on some machines with buggy watchdogs. Fix it - i.e. restore old behaviour. Thanks to Sitsofe Wheeler and Adrian Bunk for catching the problem and Maciej W. Rozycki for explanation what is going on there. Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com> CC: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
