ACPI extended IRQ resources may contain a ResourceSource to specify an alternate interrupt controller. Introduce acpi_irq_get and use it to implement ResourceSource/IRQ domain mapping. The new API is similar to of_irq_get and allows re-initialization of a platform resource from the ACPI extended IRQ resource, and provides proper behavior for probe deferral when the domain is not yet present when called.

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.
