commitd3c976c14aupstream. Previously, %g2 would end up with the value PAGE_SIZE, but after the commit mentioned below it ends up with the value 1 due to being reused for a different purpose. We need it to be PAGE_SIZE as we use it to step through pages in our demap loop, otherwise we set different flags in the low 12 bits of the address written to, thereby doing things other than a nucleus page flush.

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.
