Since commit 7a5b4e16c880f8350d255dc188f81622905618c1, simpad devices don't boot anymore, since platform devices are registered too early. Fix by moving the registration from map_io to arch_initcall as done on other sa1100 boards.

2011-01-03ARM: pxa: fix page table corruption on resumeAric D. Blumer1-2/+2
Before this patch, the following error would sometimes occur after a resume on pxa3xx: /path/to/mm/memory.c:144: bad pmd 8040542e. The problem was that a temporary page table mapping was being improperly restored. The PXA3xx resume code creates a temporary mapping of resume_turn_on_mmu to avoid a prefetch abort. The pxa3xx_resume_after_mmu code requires that the r1 register holding the address of this mapping not be modified, however, resume_turn_on_mmu does modify it. It is mostly correct in that r1 receives the base table address, but it may also get other bits in 13:0. This results in pxa3xx_resume_after_mmu restoring the original mapping to the wrong place, corrupting memory and leaving the temporary mapping in place.

If the irqsoff tracer is in use, stop tracing the interrupt disable interval when returning to userspace. Tracing userspace execution time as interrupts disabled time is not helpful for kernel performance analysis purposes. Only do so if the irqsoff tracer is enabled, to avoid overhead for lockdep, which doesn't care.

2010-12-23ARM: sched_clock: provide common infrastructure for sched_clock()Russell King4-0/+191
Provide common sched_clock() infrastructure for platforms to use to create a 64-bit ns based sched_clock() implementation from a counter running at a non-variable clock rate. This implementation is based upon maintaining an epoch for the counter and an epoch for the nanosecond time. When we desire a sched_clock() time, we calculate the number of counter ticks since the last epoch update, convert this to nanoseconds and add to the epoch nanoseconds. We regularly refresh these epochs within the counter wrap interval. We perform a similar calculation as above, and store the new epochs. We read and write the epochs in such a way that sched_clock() can easily (and locklessly) detect when an update is in progress, and repeat the loading of these constants when they're known not to be stable. The one caveat is that sched_clock() is not called in the middle of an update. We achieve that by disabling IRQs. Finally, if the clock rate is known at compile time, the counter to ns conversion factors can be specified, allowing sched_clock() to be tightly optimized. We ensure that these factors are correct by providing an initialization function which performs a run-time check.
