Regarding that loop, archs seem to fall in 3 categories:
A) Those that don't have the loop
Please clarify that this is the right thing to do (since core code already has the
loop) hence no fixing is required for this "category"
Right, those don't need any change. I had a brief look at them to double
check they had the proper need_resched() gate before calling
preempt_schedule_irq() (with no loop) and they all seem fine. Also...
B) Those that have a small need_resched() loop around the
preempt_schedule_irq() callsite
C) Those that branch to some more generic code further up the entry code
and eventually branch back to preempt_schedule_irq()
arc, m68k, nios2 fall in A)
I forgot to include parisc in here.
