e5ecfde222 util: python implementation of a routine that will sort includes
I didn't realize that the perl version existed when I started this,
this version has a lot more features than the previous one since it will
sort and separate python, system, and m5 headers in separate groups, it
will remove duplicates, it will also convert c headers to stl headers

07815c3379 region: add a utility class for keeping track of regions of some range
This is basically like the range_map stuff in src/base (range already
exists in Python).  This code is like a set of ranges.  I'm using it
to keep track of changed lines in source code, but it could be use to
keep track of memory ranges and holes in memory regions.  It could
also be used in memory allocation type stuff.  (Though it's not at all
optimized.)

332adcdd1a Sim: Fix Simulation.py to allow more than 1 core for standard switching.
This patch moves the assignment of testsys.switch_cpus, testsys.switch_cpus_1,
switch_cpu_list, and switch_cpu_list1 outside of the for loop so they are
assigned only once, after switch_cpus and switch_cpus_1 are constructed.

6b69890493 ARM: Fix checkpoint restoration into O3 CPU and the way O3 switchCpu works.
This change fixes a small bug in the arm copyRegs() code where some registers
wouldn't be copied if the processor was in a mode other than MODE_USER.
Additionally, this change simplifies the way the O3 switchCpu code works by
utilizing TheISA::copyRegs() to copy the required context information
rather than the adhoc copying that goes on in the CPU model. The current code
makes assumptions about the visibility of int and float registers that aren't
true for all architectures in FS mode.

7dde557fdc O3: Tighten memory order violation checking to 16 bytes.
The comment in the code suggests that the checking granularity should be 16
bytes, however in reality the shift by 8 is 256 bytes which seems much
larger than required.

0788ea7b3b hammer: fixed dma uniproc error
Fixed an error reguarding DMA for uninprocessor systems.  Basically removed an
overly agressive optimization that lead to inconsistent state between the
cache and the directory.

01fc529bb2 CacheMemory: add allocateVoid() that is == allocate() but no return value.
This function duplicates the functionality of allocate() exactly, except that it does not return
a return value.  In protocols where you just want to allocate a block
but do not want that block to be your implicitly passed cache_entry, use this function.
Otherwise, SLICC will complain if you do not consume the pointer returned by allocate(),
and if you do a dummy assignment Entry foo := cache.allocate(address), the C++
compiler will complain of an unused variable.  This is kind of a hack to get around
those issues, but suggestions welcome.

d857105b5a Ruby: Simplify SLICC and Entry/TBE handling.
Before this changeset, all local variables of type Entry and TBE were considered
to be pointers, but an immediate use of said variables would not be automatically
deferenced in SLICC-generated code.  Instead, deferences occurred when such
variables were passed to functions, and were automatically dereferenced in
the bodies of the functions (e.g. the implicitly passed cache_entry).

This is a more general way to do it, which leaves in place the
assumption that parameters to functions and local variables of type AbstractCacheEntry
and TBE are always pointers, but instead of dereferencing to access member variables
on a contextual basis, the dereferencing automatically occurs on a type basis at the
moment a member is being accessed.  So, now, things you can do that you couldn't before
include:

Entry foo := getCacheEntry(address);
cache_entry.DataBlk := foo.DataBlk;

or

cache_entry.DataBlk := getCacheEntry(address).DataBlk;

or even

cache_entry.DataBlk := static_cast(Entry, pointer, cache.lookup(address)).DataBlk;

322b9ca2c5 Ruby: Add new object called WireBuffer to mimic a Wire.
This is a substitute for MessageBuffers between controllers where you don't
want messages to actually go through the Network, because requests/responses can
always get reordered wrt to one another (even if you turn off Randomization and turn on Ordered)
because you are, after all, going through a network with contention. For systems where you model
multiple controllers that are very tightly coupled and do not actually go through a network,
it is a pain to have to write a coherence protocol to account for mixed up request/response orderings
despite the fact that it's completely unrealistic.  This is *not* meant as a substitute for real
MessageBuffers when messages do in fact go over a network.

225e67f531 Ruby: pass Packet->Req->contextId() to Ruby.
It is useful for Ruby to understand from whence request packets came.
This has all request packets going into Ruby pass the contextId value, if
it exists.  This supplants the old libruby proc_id value passed around in
all the Messages, so I've also removed the unused unsigned proc_id; member
generated by SLICC for all Message types.

e0fdd86fd9 mips: cleanup ISA-specific code
***
(1): get rid of expandForMT function
MIPS is the only ISA that cares about having a piece of ISA state integrate
multiple threads so add constants for MIPS and relieve the other ISAs from having
to define this. Also, InOrder was the only core that was actively calling
this function
* * *
(2): get rid of corespecific type
The CoreSpecific type was used as a proxy to pass in HW specific params to
a MIPS CPU, but since MIPS FS hasnt been touched for awhile, it makes sense
to not force every other ISA to use CoreSpecific as well use a special
reset function to set it. That probably should go in a PowerOn reset fault
 anyway.
