Although on HSW/BDW there is only a single display global power well, it's programmed the same way as other GEN9+ power wells. This also means we can get at the HSW/BDW request and status flags the same way it's done on GEN9+ by assigning the corresponding HSW/BDW power well ID. This ID was assigned in a recent patch, so we can now switch to using the same macros everywhere on HSW+. Updating the HSW power well control register with RMW is not strictly necessary, but this will allow us to use the same code for GEN9+.

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.
