Subject: parisc: Switch to generic sched_clock implementation

From: Helge Deller <[email protected]>

commit 43b1f6abd59063a088416a0df042b36450f91f75 upstream.

Drop the open-coded sched_clock() function and replace it by the provided GENERIC_SCHED_CLOCK implementation. We have seen quite some hung tasks in the past, which seem to be fixed by this patch.
