2011-04-04	ARM: Fix table walk going on while ASID changes error	Ali Saidi

2011-01-18	O3: Fixes the way prefetches are handled inside the iew unit.	Matt Horsnell
	This patch prevents the prefetch being added to the instCommit queue twice.
2011-01-03	Make commenting on close namespace brackets consistent.	Steve Reinhardt
	Ran all the source files through 'perl -pi' with this script: s\|\s(};?\s)?/\\s(end\s)?namespace\s(\S+)\s\/(\s})?\|} // namespace $3\|; s\|\s};?\s//\s(end\s)?namespace\s(\S+)\s\|} // namespace $2\n\|; s\|\s};?\s//\s(\S+)\snamespace\s\|} // namespace $1\n\|; Also did a little manual editing on some of the arch/*/isa_traits.hh files and src/SConscript.
2010-09-13	Faults: Pass the StaticInst involved, if any, to a Fault's invoke method.	Gabe Black
	Also move the "Fault" reference counted pointer type into a separate file, sim/fault.hh. It would be better to name this less similarly to sim/faults.hh to reduce confusion, but fault.hh matches the name of the type. We could change Fault to FaultPtr to match other pointer types, and then changing the name of the file would make more sense.
2010-08-25	ARM: Adding a bogus fault that does nothing.	Min Kyu Jeong
	This fault can used to flush the pipe, not including the faulting instruction. The particular case I needed this was for a self-modifying code. It needed to drain the store queue and force the following instruction to refetch from icache. DCCMVAC cp15 mcr instruction is modified to raise this fault.

2010-08-23	ARM: adding genMachineCheckFault() stub for ARM that doesn't panic	Min Kyu Jeong

2010-06-02	ARM: Implement the ARM TLB/Tablewalker. Needs performance improvements.	Ali Saidi

2010-06-02	ARM: Implement ARM CPU interrupts	Ali Saidi

2010-06-02	ARM: Implement and update the DFSR and IFSR registers on faults.	Gabe Black

2010-06-02	ARM: Trigger system calls from the SupervisorCall invoke method.	Gabe Black
	This simplifies the decoder slightly, and makes the system call mechanism very slightly more realistic.
2010-06-02	ARM: Rework how unrecognized/unimplemented instructions are handled.	Gabe Black
	Instead of panic immediately when these instructions are executed, an UndefinedInstruction fault is returned. In FS mode (not currently implemented), this is the fault that should, to my knowledge, be triggered in these situations and should be handled using the normal architected mechanisms. In SE mode, the fault causes a panic when it's invoked that gives the same information as the instruction did. When/if support for speculative execution of ARM is supported, this will allow a mispeculated and unrecognized and/or unimplemented instruction from causing a panic. Only once the instruction is going to be committed will the fault be invoked, triggering the panic.
2009-11-10	ARM: Implement fault classes.	Gabe Black
	Implement some fault classes using the curriously recurring template pattern, similar to SPARCs.
2009-04-05	arm: add ARM support to M5	Stephen Hines
