mainlining shenanigans
8eaa0648d7
The BROM has a branch that checks if the primary core is hotplugging. If the magic flag is set, execution jumps to the address set in the software entry register. (Secondary cores always branch to the that address.) This patch sets the flags that makes BROM jump execution on the primary core (cpu0) to the SMP software entry code when the core is powered back up. After it is re-integrated into the system, the flag is cleared. A custom .cpu_can_disable callback that returns true for all cpus, so that cpu0 can really be brought down.

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.
