powerpc: Reduce pseries panic timeout from 180s to 10s
We've had a 180 second panic timeout on ppc64 for as long as I can remember. This patch reduces it to 10 seconds on pseries for a few reasons: - Almost all pseries machines have a hypervisor console so panic output will be available in a scrollback buffer. - The 180 seconds impacts our availability, users (other than kernel hackers) just want the box to come back around so it can continue its work. - I spend a lot of my life staring at the 180 second panic timeout. Many pseries machines take minutes to power cycle, so it's quicker to sit through the 180 seconds than it is to power cycle.
