In commit fda812ebe3 ("drm/amdkfd: gfx12 context save/restore trap handler fixes")
the following fix was introduced but incorrectly restricted to gfx12.
The same issue and a corresponding fix apply to gfx10 and gfx11.
Do not overwrite TRAPSTS.{SAVECTX,HOST_TRAP} when restoring this
register. Both of these fields can assert while the wavefront is
running the trap handler.

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 reStructuredText 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.
