Alex Deucher 4caf84498f drm/amdgpu: use the same HDP flush registers for all nbio 2.3.x
[ Upstream commit 98a90f1f0f ]

Align RDNA2.x with other asics.  One HDP bit per SDMA instance,
aligned with firmware.  This is effectively a revert of
commit 369b7d04ba ("drm/amdgpu/nbio2.3: don't use GPU_HDP_FLUSH bit 12").
On further discussions with the relevant hardware teams,
re-align the bits for SDMA.

Fixes: 369b7d04ba ("drm/amdgpu/nbio2.3: don't use GPU_HDP_FLUSH bit 12")

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.
