flush_tlb_page is for flushing user pages, so it should not be using flush_tlb_one (which flushes all pages). This patch implements it with the flush_tlb_range, which is a user flush that does the right thing. flush_tlb_one is made static to mm/tlb.c because it's a bit confusing. It is used in do_page_fault to flush the kernel non-linear mappings, so that is replaced with flush_tlb_kernel_page. The end result is that functionality is identical.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
