CPU->checkInterrupts bool is inconsistent, and i think should eventually be phased out. For now, I've just assumed that CPU->checkInterrupts() is the way to fast path a CPU if you have no interrupts by having a simple bitfield in each ISA to determine whether interrupts are pending. getInterrupts has been mostly filled in. src/arch/sparc/interrupts.hh: fill in how we do interrupts on sparc a little bit. 1) create a bitfield for interrupts, and check that in checkInterrupts() to fast path CPU. 2) fill in getInterrupts() a little bit. also, update the bitfield access to be HPSTATE::hpriv, etc. src/arch/sparc/ua2005.cc: 1) update formatting 2) change the way interrupts are done to use the new way to tickle the CPU. src/cpu/base.cc: src/cpu/base.hh: overload the post_interrupt function for SPARC interrupts - which are only denoted by a single int value. --HG-- extra : convert_revision : 9074a003eff37a40dcce78f56d20f6cbcc453eb5
