Subject: RSE Behavior on Interruptions

Let's assume a user program just has been interrupted.
The RSE can continue spilling/filling registers on behalf of the interrupted user.
Let's assume the RSE engine touches a swapped out page.
As PSR.ic is 0, the page fault cannot be captured correctly.

Can this scenario happen to the current Linux kernel implementation?

Thanks,
