Most of the time, flush_tlb_range() is called on single pages. At the time being, flush_tlb_range() inconditionnaly calls flush_tlb_mm() which flushes at least the entire PID pages and on older CPUs like 4xx or 8xx it flushes the entire TLB table. This patch calls flush_tlb_page() instead of flush_tlb_mm() when the range is a single page.

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.
