2017-03-07	gpu-compute: Fix Python/C++ object hierarchy discrepancies	Andreas Sandberg
	The GPUCoalescer and the Shader classes have different base classes in C++ and Python. This causes subtle bugs in SWIG and compilation errors for PyBind.

2017-02-27	syscall_emul: [PATCH 15/22] add clone/execve for threading and multiprocess ↵	Brandon Potter
	simulations Modifies the clone system call and adds execve system call. Requires allowing processes to steal thread contexts from other processes in the same system object and the ability to detach pieces of process state (such as MemState) to allow dynamic sharing.

2016-04-07	mem: Remove threadId from memory request class	Mitch Hayenga
	In general, the ThreadID parameter is unnecessary in the memory system as the ContextID is what is used for the purposes of locks/wakeups. Since we allocate sequential ContextIDs for each thread on MT-enabled CPUs, ThreadID is unnecessary as the CPUs can identify the requesting thread through sideband info (SenderState / LSQ entries) or ContextID offset from the base ContextID for a cpu. This is a re-spin of 20264eb after the revert (bd1c6789) and includes some fixes of that commit.
2016-03-17	syscall_emul: move mmapGrowsDown() to LiveProcess	Steve Reinhardt
	The mmapGrowsDown() method was a static method on the OperatingSystem class (and derived classes), which worked OK for the templated syscall emulation methods, but made it hard to access elsewhere. This patch moves the method to be a virtual function on the LiveProcess method, where it can be overridden for specific platforms (for now, Alpha). This patch also changes the value of mmapGrowsDown() from being false by default and true only on X86Linux32 to being true by default and false only on Alpha, which seems closer to reality (though in reality most people use ASLR and this doesn't really matter anymore). In the process, also got rid of the unused mmap_start field on LiveProcess and OperatingSystem mmapGrowsUp variable.
