Ian Campbell noticed a missing TLB flush which was causing the USB 
crashes/failures when booting the pvops dom0 kernel.  With that fixed, 
enabling USB boots reliably and seems to work.

Its quite possible this will also improve matters with ATA/SATA 
controllers, though I haven't tested it so far.

Anyway, its a significant fix and its worth trying the current pvops 
patch queue again.  Please tell me what you find.

Thanks,
    J
