This is wrong, since the platform_bus functions expect the 'struct device_driver' to be wrapped up in a 'struct platform_driver' which provides some additional callbacks (like suspend_late, resume_early). The effect may be that platform_suspend_late() uses bogus data outside the device_driver struct as a pointer pointer to the device driver's suspend_late() function or other hard to reproduce failures."(Lothar Wassmann) Signed-off-by: Ming Lei <tom.leiming@gmail.com> Acked-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

The tick rate define (ORION5X_TCLK) was removed in favor of a runtime detection. The quick fix is to add the define in the watchdog driver. The fix is not correct for all supported orion5x platforms, but since the supported platforms right now are 133 Mhz and 166 Mhz, it won't be _that_ far off. ;-) A fix that uses the runtime-determined timer tick rate will be applied later.

This causes the watchdog platform_device to never be registered, and therefore the driver not to be initialized. This patch: - updates the platform support code to use AT91SAM9X_WATCHDOG. - includes <linux/io.h> to fix compile error (same fix as was applied to at91rm9200_wdt.c) - fixes comment regarding watchdog clock-rates in at91rm9200.

This bug seemingly caused various random behavior, with Frans Pop reporting that X.org just silently hung at startup and Rafael Wysocki reports the fan spinning with full speed. See http://lkml.org/lkml/2008/12/3/178 http://bugzilla.kernel.org/show_bug.cgi?id=12162 The problem seems to have been triggered by "[WATCHDOG] iTCO_wdt : problem with rebooting on new ICH9 based motherboards" (commit 7cd5b08be3c489df11b559fef210b81133764ad4), but the bogus code existed before that too (in the "supermicro_old_pre_stop()" function), it just apparently never showed up due to different logic. In that commit the broken code got moved around and now gets executed much more. Reported-by: Rafael J.

| * | [WATCHDOG] hpwdt: Fix kdump when using hpwdtBernhard Walle2008-12-011-1/+1

The panic kernel either does not start at all or crash in various places. The problem is that hpwdt_pretimeout is registered with register_die_notifier() with the highest possible priority. Because it returns NOTIFY_STOP, the crash_nmi_callback which is also registered with register_die_notifier() is never executed. This causes the shutdown of other CPUs to fail. Reverting the order is no option: The crash_nmi_callback executes HLT and so never returns normally. Because of that, it must be executed as last notifier, which currently is done. So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.
