Junwei Zhang 27f6d61036 drm/amdgpu: fix before and after mapping judgement for replace mapping
If the before mapping is 1 page size, so its start and last will be same.
Thus below condition will become false, then to free the before mapping.
   > if (before->it.start != before->it.last)
But in this case, we need the before mapping of 1 page size.
So does after mapping.

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.
