O(1) and kdb

[anton wilson]

Not sure if anyone's interested, but to change KDB to use the O(1) scheduler 
just replace 

+                          task_has_cpu(p), p->processor,

with

+                          (p->array != NULL), p->cpu,

in the common patch at:

+int
+kdb_ps(int argc, const char **argv, const char **envp, struct pt_regs *regs)
+{
+       struct task_struct      *p;
+
+       kdb_printf("%-*s Pid      Parent   [*] cpu  State %-*s Command\n",
+               (int)(2*sizeof(void *))+2, "Task Addr",
+               (int)(2*sizeof(void *))+2, "Thread");
+       for_each_task(p) {
+               kdb_printf("0x%p %08d %08d  %1.1d  %3.3d  %s  0x%p%c%s\n",
+                          (void *)p, p->pid, p->p_pptr->pid,
+                          task_has_cpu(p), p->processor,
+                          (p->state == 0)?"run ":(p->state>0)?"stop":"unrn",
+                          (void *)(&p->thread),
+                          (p == current) ? '*': ' ',
+                          p->comm);
+       }
+
+       return 0;
+}
