2010-06-02	ARM: Allow ARM processes to start in Thumb mode.	Gabe Black

2009-10-30	Syscalls: Make system calls access arguments like a stack, not an array.	Gabe Black
	When accessing arguments for a syscall, the position of an argument depends on the policies of the ISA, how much space preceding arguments took up, and the "alignment" of the index for this particular argument into the number of possible storate locations. This change adjusts getSyscallArg to take its index parameter by reference instead of value and to adjust it to point to the possible location of the next argument on the stack, basically just after the current one. This way, the rules for the new argument can be applied locally without knowing about other arguments since those have already been taken into account implicitly. All system calls have also been changed to reflect the new interface. In a number of cases this made the implementation clearer since it encourages arguments to be collected in one place in order and then used as necessary later, as opposed to scattering them throughout the function or using them in place in long expressions. It also discourages using getSyscallArg over and over to retrieve the same value when a temporary would do the job.

2009-07-29	ARM: Fix an instruction in the cmpxchg kernel provided routine.	Gabe Black
	The instruction was encoded as a load instead of the intended store.

2009-06-09	ARM: Hook in the mmap2 system call. Make ArmLinuxProcess handle 5,6 syscall ↵	Gabe Black
	params.
2009-06-09	ARM: Add a memory_barrier function to the "comm page".	Gabe Black
	This function doesn't actually provide a memory barrier (I don't think they're implemented) and instead just returns.
2009-06-09	ARM: Add a cmpxchg implementation to the "comm page".	Gabe Black
	This implementation does what it's supposed to (I think), but it's not atomic and doesn't have memory barriers like the kernel's version.
2009-06-09	ARM: Implement TLS. This is not tested.	Gabe Black

2009-06-09	ARM: Make ArmLinuxProcess understand "ARM private" system calls.	Gabe Black
