2011-04-14sched: Provide scheduler_ipi() callback in response to smp_send_reschedule()Peter Zijlstra
For future rework of try_to_wake_up() we'd like to push part of that function onto the CPU the task is actually going to run on. In order to do so we need a generic callback from the existing scheduler IPI. This patch introduces such a generic callback: scheduler_ipi() and implements it as a NOP. BenH notes: PowerPC might use this IPI on offline CPUs under rare conditions!

2010-10-29MIPS: Octeon: Apply CN63XXP1 errata workarounds.David Daney
The CN63XXP1 needs a couple of workarounds to ensure memory is not written in unexpected ways. All PREF with hints in the range 0-4,6-24 are replaced with PREF 28.

2010-10-29MIPS: Octeon: Rewrite DMA mapping functions.David Daney

2010-08-05MIPS: Octeon: Allow more than 3.75GB of memory with PCIeDavid Daney
We reserve the 3.75GB - 4GB region of PCIe address space for device to device transfers, making the corresponding physical memory under direct mapping unavailable for DMA. To allow for PCIe DMA to all physical memory we map this chunk of physical memory with BAR1. Because of the resulting discontinuity in the mapping function, we remove a page of memory at each end of the range so multi-page DMA buffers can never be allocated that span the range.

2010-08-05MIPS: Octeon: Fix fixup_irqs for HOTPLUG_CPUDavid Daney
The original version went behind the back of everything, leaving things in an inconsistent state. Now we use the irq_set_affinity() to do the work for us. This has the advantage that the IRQ core's view of the affinity stays consistent.

2010-08-05MIPS: Octeon: Improve interrupt handling.David Daney
The main change is to change most of the IRQs from handle_percpu_irq to handle_fasteoi_irq. This necessitates extracting all the .ack code to common functions that are not exposed to the irq core. The affinity code now acts more sanely, by doing round-robin distribution instead of broadcasting. Because of the change to handle_fasteoi_irq and affinity, some of the IRQs had to be split into separate groups with their own struct irq_chip to prevent undefined operations on specific IRQ lines.
