The function unisys_vmcall was returning VMCALL specific errors and the calling code was ignoring which error was actually returned. Instead we should be mapping the VMCALL error into a proper Linux error and then returning that, since we now have an error we know what to do with, we don't have to drop it but we can send it up the stack.

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.
