mainlining shenanigans

Some powerpc platforms use this to move IRQs away from a CPU being unplugged. This function has several bugs such as not taking the right locks or failing to NULL check pointers. There's a new generic function doing exactly the same thing without all the bugs, so let's use it instead. mpe: The obvious place for the select of GENERIC_IRQ_MIGRATION is on HOTPLUG_CPU, but that doesn't work. On some configs PM_SLEEP_SMP will select HOTPLUG_CPU even though its dependencies are not met, which means the select of GENERIC_IRQ_MIGRATION doesn't happen. That leads to the build breaking. Fix it by moving the select of GENERIC_IRQ_MIGRATION to SMP. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> |

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.
