The machine__set_kernel_mmap() is to setup addresses of the kernel map using external info. But it has a check when the address is given from an incorrect input which should have the start and end address of 0 (i.e. machine__process_kernel_mmap_event). But we also use the end address of 0 for a valid input so change it to check both start and end addresses.

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.
