gic_set_cpu will directly use irq_desc[]. If CONFIG_SPARSE_IRQ is enabled, there is no irq_desc[]. So we need use irq_to_desc(irq) to get the descriptor for irq.

Software generated interrupts (SGI) are used for IPIs by the kernel. While previous revisions of the GIC hardware were specified not to implement enable bits for SGIs, more recent hardware is now permitted to implement these bits in a per-CPU banked register. The priority registers for the PPI and SGIs are also per-CPU banked registers, so ensure that these are also appropriately initialized.

Masking in the ack callback fails to work with handle_percpu_irq and handle_edge_irq. The interrupt stays disabled after the first invocation since percpu and edge irq do not unmask an interrupt after handling it. For handle_level_irq masking in the ack is redundant because ack is always called after mask in the mask_ack function. Masking in the ack function is required only when __do_IRQ was used instead of flow handlers, but using __do_IRQ has been deprecated. Remove the masking of interrupt from the ack callback.

Impact: change existing irq_chip API Not much point with gentle transition here: the struct irq_chip's setaffinity method signature needs to change. Fortunately, not widely used code, but hits a few architectures. Note: In irq_select_affinity() I save a temporary in by mangling irq_desc[irq].affinity directly. Ingo, does this break anything?

No need for the cascade irq function to have a "fastcall" annotation. Fix the range checking for valid IRQ numbers - comparing the value returned by the GIC with NR_IRQS is meaningless since we translate the GIC irq number to a Linux IRQ number afterwards. Check the GIC returned IRQ number is within limits first, then add the IRQ offset, and only then compare with NR_IRQS. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

Patch from David Brownell ARM genirq cleanups/updates: - Start switching platforms to newer APIs * use "irq_chip" name, not "irqchip" * providing irq_chip.name - Show irq_chip.name in /proc/interrupts, like on x86. This update a bit more than half of the ARM code. The irq_chip.name values were chosen to match docs (if I have them) or be otherwise obvious ("FPGA", "CPLD", or matching the code).
