mainline inclusion
from mainline-v6.9-rc1
commit 2aaa1995a94a3187e52ddb9f127fa1307ee8ad00
category: feature
bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I9A5BW
CVE: N/A
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=2aaa1995a94a3187e52ddb9f127fa1307ee8ad00



-------------------------------------

Notify a fatal error condition and optionally reset the device in
the following cases:
  * if the device reports an uncorrectable fatal error through an
    interrupt
  * if the heartbeat feature detects that the device is not
    responding

This patch is based on earlier work done by Shashank Gupta.
