[parisc-linux] small patch for cpu_idle?

[Randolph Chung <randolph@tausq.org>]

It appears to me that our cpu_idle is not quite right... what do you
guys think about this:

Index: process.c

        current->counter = -100;
 
        while (1) {
-               while (!current->need_resched) {
-               }
+               while (!current->need_resched) 
+                       continue;
                schedule();
                check_pgt_cache();
        }

otherwise when cpu_idle gets called we might get stuck in an inf loop
(which happens, for example, when fsck requires manual intervention on
startup).
