set the softint appropriately on an timer compare interrupt
there is no interrupt_level_0 interrupt, so start the list at 0x40 so the adding is done correctly src/arch/sparc/faults.cc: there is no interrupt_level_0 interrupt, so start the list at 0x40 so the adding is done correctly src/arch/sparc/faults.hh: correct protection defines src/arch/sparc/ua2005.cc: set the softint appropriately on an timer compare interrupt --HG-- extra : convert_revision : f41c10ec78db973b3f856c70b58a17f83b60bbe2
