2011-12-21ARM: gic: Use affinity hint to set multiple CPUs for IRQAlex Frid
GIC IRQ affinity is currently set to one CPU only - the 1st cpu in the requested mask. This commit adds option to set IRQ affinity to all cpus present in affinity_hint and requested masks. The option is enabled by default on Tegra architecture starting with Tegra3. (cherry picked from commit 09f7ef4f28a6e18188649c40848252bc18a6646c) Change-Id: I0d655f1d39170382f3372294172ed6d02dc0ad49 Signed-off-by: Alex Frid <afrid@nvidia.com> Reviewed-on: http://git-master/r/69328 Reviewed-by: Lokesh Pathak <lpathak@nvidia.com> Tested-by: Lokesh Pathak <lpathak@nvidia.com>

2011-07-22PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.Ralf Baechle
Aside of the usual motivation for constification, this function has a history of being abused a hook for interrupt and other fixups so I turned this function const ages ago in the MIPS code but it should be done treewide. Due to function pointer passing in varous places a few other functions had to be constified as well.

2011-07-21ARM: GIC: avoid routing interrupts to offline CPUsRussell King
The irq_set_affinity() method can be called with masks which include offline CPUs. This allows offline CPUs to have interrupts routed to them by writing to /proc/irq/*/smp_affinity after hotplug has taken a CPU offline. Fix this by ensuring that we select a target CPU present in both the required affinity and the online CPU mask. Ensure that we return IRQ_SET_MASK_OK (which happens to be 0) on success to ensure generic code copies the new mask into the irq_data structure.

2011-07-21ARM: CPU hotplug: fix abuse of irqdesc->nodeRussell King

2011-07-04ARM: dmabounce: no need to check dev->bus type in needs_bounce functionRussell King
