The pattern of a power well backing a set of pipe IRQ or VGA functionality applies to all HSW+ platforms. Using power well attributes instead of platform checks to decide whether to init/reset pipe IRQs and VGA correspondingly is cleaner and it allows us to unify the HSW/BDW and GEN9+ power well code in follow-up patches. Also use u8 for pipe_mask in related helpers to match the type in the power well struct. v2: - Use u8 instead of u32 for irq_pipe_mask. (Ville) v3: - Use u8 for pipe_mask in related helpers too for clarity.

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.
