memblock_is_region_memory() invoke memblock_search() to see whether the base address is in the memory region. If it fails, idx would be -1. Then, it returns 0. If the memblock_search() returns a valid index, it means the base address is guaranteed to be in the range memblock.memory.regions[idx]. Because of this, it is not necessary to check the base again. This patch removes the check on "base".

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.
