2015-07-22genirq/MSI: Reorginize struct msi_desc to prepare for support of generic MSIJiang Liu
Reorganize struct msi_desc so it could be reused by other MSI drivers. We have the following layout now: struct msi_desc { /* Shared device/bus independent data */ ... union { /* PCI specific data */ struct { ... }; }; }; We need to have anonymous union and a anonymous structure for the PCI fields, otherwise we would have to change all instances using these fields. For non PCI devices we will enforce a proper namespace and a non anonymous structure.

2015-07-22irqchip: omap-intc: Improve IRQ handlerFelipe Balbi
As it turns out the current IRQ number will *always* be available from SIR register which renders the reads of PENDING registers as plain unnecessary overhead. In order to catch any situation where SIR reads as zero, we're adding a WARN() to turn it into a very verbose error and users actually report it. With this patch average running time of omap_intc_handle_irq() reduced from about 28.5us to 19.8us as measured by the kernel function profiler. Tested with BeagleBoneBlack Rev A5C.
