From: John Harrison <John.C.Harrison@xxxxxxxxx> If a context has already been registered prior to first submission then context init code was not being called. The noticeable effect of that was the scheduling priority was left at zero (meaning super high priority) instead of being set to normal. This would occur with kernel contexts at start of day as they are manually pinned up front rather than on first submission. So add a call to initialise those when they are pinned.
