Interrupt randomness in 3.14.10-rt
From: Ben Hutchings

I noticed this change between 3.14.3-rt5 and 3.14.10-rt7:
--- debian/patches/features/all/rt/random-make-it-work-on-rt.patch (revision 21522)
+++ debian/patches/features/all/rt/random-make-it-work-on-rt.patch (working copy)
-@@ -942,6 +942,12 @@ static int irq_thread(void *data)
- if (action_ret == IRQ_HANDLED)
-+ add_interrupt_randomness(action->irq, 0,
-+ desc->random_ip ^ (unsigned long) action);
(I.e. old patch included these additions, new patch doesn't.)
Evidently this was made in the announced 3.14.10-rt6, not -rt7. Was it
intentional? Now irq_desc::random_ip is set but never used.
To err is human; to really foul things up requires a computer.
