44e5e7e053 X86: Obey the wp bit of CR0.
If cr0.wp ("write protect" bit) is clear then do not generate page faults when
writing to write-protected pages in kernel mode.

6da83b8a1b X86: Use all 64 bits of the lstar register in the SYSCALL_64 macroop.
During SYSCALL_64, use dataSize=8 when handling new rip (ref
http://www.intel.com/Assets/PDF/manual/253668.pdf 5.8.8 IA32_LSTAR is a 64-bit
address)

2ea1aa8a4f X86: Fix JMP_FAR_I to unpack a far pointer correctly.
JMP_FAR_I was unpacking its far pointer operand using sll instead of srl like
it should, and also putting the components in the wrong registers for use by
other microcode.

5810ab121c X86: Read the LDT/GDT at CPL0 when executing an iret.
During iret access LDT/GDT at CPL0 rather than after transition to user mode
(if I'm reading the Intel IA-64 architecture spec correctly, the contents of
the descriptor table are read before the CPL is updated).

f8fc0419c5 X86, Config: Move the setting of work count options to a separate function.
This way things that don't care about work count options and/or aren't called
by something that has those command line options set up doesn't have to build
a fake object to carry in inert values.

f5aa75fdc5 ruby: support to stallAndWait the mandatory queue
By stalling and waiting the mandatory queue instead of recycling it, one can
ensure that no incoming messages are starved when the mandatory queue puts
signficant of pressure on the L1 cache controller (i.e. the ruby memtester).

273e3d4924 mem: Added support for Null data packet
The packet now identifies whether static or dynamic data has been allocated and
is used by Ruby to determine whehter to copy the data pointer into the ruby
request.  Subsequently, Ruby can be told not to update phys memory when
receiving packets.

3a2d2223e1 x86: Timing support for pagetable walker
Move page table walker state to its own object type, and make the
walker instantiate state for each outstanding walk. By storing the
states in a queue, the walker is able to handle multiple outstanding
timing requests. Note that functional walks use separate state
elements.

52b6119228 TimingSimpleCPU: split data sender state fix
In sendSplitData, keep a pointer to the senderState that may be updated after
the call to handle*Packet. This way, if the receiver updates the packet
senderState, it can still be accessed in sendSplitData.

d9f0a8288e MessagePort: implement the virtual recvTiming function to avoid double pkt delete
Double packet delete problem is due to an interrupt device deleting a packet that the SimpleTimingPort also deletes. Since MessagePort descends from SimpleTimingPort, simply reimplement the failing code from SimpleTimingPort: recvTiming.

Separate data VCs and ctrl VCs in garnet, as ctrl VCs have 1 buffer per VC,
while data VCs have > 1 buffers per VC. This is for correct power estimations.

e396a34b01 inorder: fault handling
Maintain all information about an instruction's fault in the DynInst object rather
than any cpu-request object. Also, if there is a fault during the execution stage
then just save the fault inside the instruction and trap once the instruction
tries to graduate

68d962f8af inorder: add a fetch buffer to fetch unit
Give fetch unit it's own parameterizable fetch buffer to read from. Very inefficient
(architecturally and in simulation) to continually fetch at the granularity of the
wordsize. As expected, the number of fetch memory requests drops dramatically

ab3d37d398 inorder: implement separate fetch unit
instead of having one cache-unit class be responsible for both data and code
accesses, separate code that is just for fetch in it's own derived class off the
original base class. This makes the code easier to manage as well as handle
future cases of special fetch handling
