2014-01-24	arm: Add support for ARMv8 (AArch64 & AArch32)	ARM gem5 Developers
	Note: AArch64 and AArch32 interworking is not supported. If you use an AArch64 kernel you are restricted to AArch64 user-mode binaries. This will be addressed in a later patch. Note: Virtualization is only supported in AArch32 mode. This will also be fixed in a later patch.

2014-01-24	cpu: Add CPU support for generatig wake up events when LLSC adresses are ↵	Ali Saidi
	snooped. This patch add support for generating wake-up events in the CPU when an address that is currently in the exclusive state is hit by a snoop. This mechanism is required for ARMv8 multi-processor support.
2013-01-07	o3: Fix issue with LLSC ordering and speculation	Ali Saidi
	This patch unlocks the cpu-local monitor when the CPU sees a snoop to a locked address. Previously we relied on the cache to handle the locking for us, however some users on the gem5 mailing list reported a case where the cpu speculatively executes a ll operation after a pending sc operation in the pipeline and that makes the cache monitor valid. This should handle that case by invaliding the local monitor.

2011-04-04	ARM: Use CPU local lock before sending load to mem system.	Ali Saidi
	This change uses the locked_mem.hh header to handle implementing CLREX. It simplifies the current implementation greatly.
