The Broadcom Brahma-B15 CPU readahead cache registers will be restored to their Power-on-Reset values after a S3 suspend/resume cycles, so we want to restore what we had enabled before. Another thing we want to take care of is disabling the read-ahead cache prior to suspending to avoid any sort of side effect with the spinlock we need to grab to serialize register accesses.

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.
