There are a few places where we want to mask all exceptions. Today we do this in a piecemeal fashion, typically we expect the caller to have masked irqs and the arch code masks debug exceptions, ignoring serror which is probably masked. Make it clear that 'mask all exceptions' is the intention by adding helpers to do exactly that. This will let us unmask SError without having to add 'oh and SError' to these paths.

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.
