Current rmap code can miss a VMA that maps PTE-mapped THP if the first suppage of the THP was unmapped from the VMA. We need to walk rmap for the whole range of offsets that THP covers, not only the first one. vma_address() also need to be corrected to check the range instead of the first subpage.

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.
