Pull more ARM updates from Russell King. This got a fair number of conflicts with the split, but also with some other sparse-irq and header file include cleanups.

cs5535-clockevt: Allow the MFGPT IRQ to be shared

2012-03-06T13:17:45Z

Shared timer IRQs are not a good solution, however the Geode platform has no APIC, IRQs are a scarce resource and there is no technical reason to forbid it rightaway. Increased latencies and overhead due to sharing are still better than a driver refusing to load.

cs5535-clockevt: Don't ignore MFGPT on SMP-capable kernels

2012-03-06T13:17:44Z

On SMP-capable kernels (e.g. generic distro kernel) the cs5535-clockevt driver loads but is not actually used. Setting cpumask to cpu_all_mask works for UP-only kernels, but if compiled for SMP - though still running on the same UP hardware - kernel/time/tick-common.c:tick_check_new_device() reads this as "non-cpu-local" and silently ignores the device. If we leave cpumask unset clockevents_register_device() will initialize it and the cs5535-clockevt driver will be used no matter how the kernel was compiled. Should anyone ever manage to stick a CS553x in an SMP system (is this even possible?) then a warning will be printed. This is fine as the cs5535-clockevt driver was never written/tested for SMP. If bisecting led you here this patch may have exposed a pre-existing MFGPT problem. Configure for UP-only and re-check.

ARM: at91/tc/clocksource: Add 32 bit variant to Timer Counter

2012-03-01T12:38:49Z

Some SoC have a 32 bit variant of Timer Counter Blocks. We do not need the chaining of two 16 bit counters anymore for them. The SoC nature is deduced from the device tree "compatible" string. For non-device-tree configurations, backward compatibility is maintained by using the default 16 bit counter configuration. This patch addresses both the atmel_tclib and its user: tcb_clksrc clocksource. Signed-off-by: Nicolas Ferre Acked-by: Jean-Christophe PLAGNIOL-VILLARD Acked-by: Grant Likely
