If we store the platform as a bitmask, and convert the IS_PLATFORM macro to use it, we allow the compiler to merge the IS_PLATFORM(a) || IS_PLATFORM(b) || ... checks into a single conditional. As a secondary benefit this saves almost 1k of text: text data bss dec hex filename -1460254 60014 3656 1523924 1740d4 drivers/gpu/drm/i915/i915.ko +1459260 60026 3656 1522942 173cfe drivers/gpu/drm/i915/i915.ko v2: Removed the infamous -1.

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.
