All our useful entry points into the hypervisor are starting by saving x0 and x1 on the stack. Let's move those into the vectors by introducing macros that annotate whether a vector is valid or not, thus indicating whether we want to stash registers or not. The only drawback is that we now also stash registers for el2_error, but this should never happen, and we pop them back right at the start of the handling sequence.

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.
