[PATCH v4 0/2] drm/xe/guc: Handle GuC local uncorrectable error notifications

[Zhanjun Dong <zhanjun.dong@intel.com>]

Add support for the GuC uncorrectable local error G2H notification and
opt in to the feature when the submission ABI exposes it.
Preserve HW error state in wedged mode 2 to help debug the root cause of
the error.
