Yifan Zhang c77c617e26 Revert "drm/amdgpu/gfx10: enlarge CP_MEC_DOORBELL_RANGE_UPPER to cover full doorbell."
commit baacf52a473b24e10322b67757ddb92ab8d86717 upstream.

This reverts commit 1c0b0efd148d5b24c4932ddb3fa03c8edd6097b3.

Reason for revert: Side effect of enlarging CP_MEC_DOORBELL_RANGE may
cause some APUs fail to enter gfxoff in certain user cases.

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.
