Saving the generic chip pointer in the brcmstb_l2_intc_data prevents the need to call irq_get_domain_generic_chip(). Also don't need to save parent_irq and base there since local variables in the brcmstb_l2_intc_of_init() function are just as good. The handle_edge_irq flow or chained_irq_enter takes care of the acknowledgment of the interrupt so it is redundant to clear it in brcmstb_l2_intc_irq_handle(). irq_linear_revmap() is a fast path equivalent of irq_find_mapping() that is appropriate to use for domain controllers of this type. Defining irq_mask_ack is slightly more efficient than just implementing irq_mask and irq_ack separately.

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.
