[PATCH] m68k/mac: Avoid soft-lockup warning after mach_power_off

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Disable interrupts for power-off, like other platforms do. This prevents 
meaningless warnings from the soft-lockup detector on models with a power 
supply unit not under software control.
