The gic_set_type() function included writes to the MIPS GIC polarity, trigger & dual-trigger registers in each case of a switch statement determining the IRQs type. This is all well & good when we only have a single cluster & thus a single GIC whose register we want to update. It will lead to significant duplication once we have multi-cluster support & multiple GICs to update. Refactor this such that we determine values for the polarity, trigger & dual-trigger registers and then have a single set of register writes following the switch statement. This will allow us to write the same values to each GIC in a multi-cluster system in a later patch, rather than needing to duplicate more register writes in each case.

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.
