	Replace direct call to unserialize() on each SimObject with a pair of calls for better control over initialization in both ckpt and non-ckpt cases. If restoring from a checkpoint, loadState(ckpt) is called on each SimObject. The default implementation simply calls unserialize() if there is a corresponding checkpoint section, so we get backward compatibility for existing objects. However, objects can override loadState() to get other behaviors, e.g., doing other programmed initializations after unserialize(), or complaining if no checkpoint section is found. (Note that the default warning for a missing checkpoint section is now gone.) If not restoring from a checkpoint, we call the new initState() method on each SimObject instead. This provides a hook for state initializations that are only required when not restoring from a checkpoint. Given this new framework, do some cleanup of LiveProcess subclasses and X86System, which were (in some cases) emulating initState() behavior in startup via a local flag or (in other cases) erroneously doing initializations in startup() that clobbered state loaded earlier by unserialize().

2010-06-02	ARM: Fix SPEC2000 benchmarks in SE mode. With this patch all	Ali Saidi
	Spec2k benchmarks seem to run with atomic or timing mode simple CPUs. Fixed up some constants, handling of 64 bit arguments, and marked a few more syscalls ignoreFunc.

2010-06-02	ARM: Added support for Access Flag and some CP15 regs (V2PCWPR, V2PCWPW, ↵	Dam Sunwoo

2010-06-02	ARM: Add a comment to vfp.cc that explains the asm statements.	Gabe Black

2010-06-02	ARM: Move some case values out of ##included files.	Gabe Black
	This will help keep the high level decode together and not have it spread into the subordinate decode stuff. The ##include lines still need to be on a line by themselves, though.

	--HG-- rename : src/arch/arm/predecoder.hh => src/arch/arm/predecoder.cc
2010-06-02	ARM: Decode to specialized conditional/unconditional versions of instructions.	Gabe Black
	This is to avoid condition code based dependences from effectively serializing instructions when the instruction doesn't actually use them.
