The idle workaround does not need to load PACATOC, and it does not need to be called within a nested function that requires LR to be saved. Load the PACATOC at entry to the idle wakeup. It does not matter which PACA this comes from, so it's okay to call before the workaround. Then apply the workaround to get the right PACA.

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.
