The gic_local_irq_domain_map() function has only one callsite in gic_irq_domain_map(), and the split between the two functions makes it unclear that they duplicate calculations & checks. Inline gic_local_irq_domain_map() into gic_irq_domain_map() in order to clean this up. Doing this makes the following small issues obvious, and the patch tidies them up: - Both functions used GIC_HWIRQ_TO_LOCAL() to convert a hwirq number to a local IRQ number. We now only do this once. Although the compiler ought to have optimised this away before anyway, the change leaves us with less duplicate code. - gic_local_irq_domain_map() had a check for invalid local interrupt numbers (intr > GIC_LOCAL_INT_FDC). This condition can never occur because any hwirq higher than those used for local interrupts is a shared interrupt, which gic_irq_domain_map() already handles separately. We therefore remove this check. - The decision of whether to map the interrupt to gic_cpu_pin or timer_cpu_pin can be handled within the existing switch statement in gic_irq_domain_map(), shortening the code a little. The change additionally prepares us nicely for the following patch of the series which would otherwise need to duplicate the check for whether a local interrupt should be percpu_devid or just percpu (ie. the switch statement from gic_irq_domain_map()) in gic_local_irq_domain_map().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
