drm/amdkfd: Add module parameter of send_sigterm
This patch adds a new kernel module parameter to amdkfd,
called send_sigterm.
This parameter specifies whether amdkfd should send the
SIGTERM signal to an HSA process, when the following conditions
occur:
1. The GPU triggers an exception regarding a kernel that was
issued by this process.
2. The HSA process isn't waiting on an event that handles
this exception.
The default behavior is not to send a SIGTERM and suffice
with a dmesg error print.
