[PATCH] powerpc/powernv: Reduce panic timeout from 180s to 10s

2014-04-30 Thread Anton Blanchard 
We've already dropped the default pseries timeout to 10s, do
the same for powernv.

 I'd vote we set it to 10s for all 64-bit machines in
 arch/powerpc/kernel/setup_64.c.

Why is 64-bit relevant?  And wouldn't such a short delay be a problem if
the crash is displayed on a monitor?

That is why we made it pseries specific in the past. Almost all our
boxes are on a virtual console and the 3 minutes of pausing just hurt
our uptimes.

If other platform maintainers prefer to keep the 3 minute pause, then
we just change the PowerNV platform.
