2011-03-29arm: at91: Cleanup irq chipThomas Gleixner
Avoid the whole lazy disable dance in the demux handler by providing a irq_disable() callback. Use the proper accessor functions and tidy up gpio_irq_handler() Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-03-29arm: davinci: Cleanup irq chip codeThomas Gleixner
Make use of the new functionality which ensures that irq_set_type is called with the chip masked. Unmask is only done when the interrupt is not disabled. Retrieve the trigger type from irq_data in unmask Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2011-03-29watchdog: softdog.c: enhancement to optionally invoke panic instead of ↵Anithra P Janakiraman
reboot on timer expiry This is needed for determining the reason for failure when a softdog timeout occurs. We use softdog to watch for critical application failures and at the minimum a snapshot of the system would help to determine the cause. In such a scenario the application could fail but there isn't a softlockup as such, hence the detect softlockup feature does not help. The patch adds a module parameter soft_panic which when set to 1 causes softdog to invoke panic instead of reboot when the softdog timer expires. By invoking panic we execute kdump if it is configured and the vmcore generated by kdump should provide atleast a minimal idea of the reason for failure.

2011-03-29x86, microcode: Unregister syscore_ops after microcode unloadedXiaotian Feng
Currently, microcode doesn't unregister syscore_ops after it's unloaded. So if we modprobe then rmmod microcode, the stale microcode syscore_ops info will stay on syscore_ops_list. Later when we're trying to reboot/halt/shutdown the machine, kernel will panic on syscore_shutdown(). With the patch applied, I can reboot/halt/shutdown my machine successfully.

When we clone a xfrm state we have to assign the replay_esn and the preplay_esn pointers to the state if we use the new replay detection method. To this end, we add a xfrm_replay_clone() function that allocates memory for the replay detection and takes over the necessary values from the original state.

2011-03-28cxgb3: Apply interrupt coalescing settings to all queuesAnton Blanchard
While testing the performance of different receive interrupt coalescing settings on a single stream TCP benchmark, I noticed two very different results. With rx-usecs=50, most of the time a connection would hit 8280 Mbps but once in a while it would hit 9330 Mbps. It turns out we are only applying the interrupt coalescing settings to the first queue and whenever the rx hash would direct us onto that queue we ran faster. With this patch applied and rx-usecs=50, I get 9330 Mbps consistently. Signed-off-by: Anton Blanchard <anton@samba.org> Acked-by: Divy Le Ray <divy@chelsio.com> Signed-off-by: David S.
