Booting a crash kernel while in an interrupt handler is likely to leave the Active Priority Registers with some state that is not relevant to the new kernel, and is likely to lead to erratic behaviours such as interrupts not firing as their priority is already active. As a sanity measure, wipe the APRs clean on startup. We make sure to wipe both group 0 and 1 registers in order to avoid any surprise. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
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.
