c913c64be2 ARM: Add a memory_barrier function to the "comm page". 
This function doesn't actually provide a memory barrier (I don't think they're
implemented) and instead just returns.

3ff1e922c2 ARM: Add a cmpxchg implementation to the "comm page". 
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.

db2b721380 inorder-tlb-cunit: merge the TLB as implicit to any memory access 
TLBUnit no longer used and we also get rid of memAccSize and memAccFlags functions added to ISA and StaticInst
since TLB is not a separate resource to acquire. Instead, TLB access is done before any read/write to memory
and the result is checked before it's sent out to memory.

6211fe5d2e inorder-float: Fix storage of FP results 
inorder was incorrectly storing FP values and confusing the integer/fp storage view of floating point operations. A big issue was knowing trying to infer when were doing single or double precision access
because this lets you know the size of value to store (32-64 bits). This isnt exactly straightforward since alpha uses all 64-bit regs while mips/sparc uses a dual-reg view. by getting this value from
the actual floating point register file, the model can figure out what it needs to store

93f2f69657 ruby: Working M5 interface and updated Ruby interface. 
This changeset also includes a lot of work from Derek Hower <drh5@cs.wisc.edu>

RubyMemory is now both a driver for Ruby and a port for M5.  Changed
makeRequest/hitCallback interface. Brought packets (superficially)
into the sequencer. Modified tester infrastructure to be packet based.
and Ruby can be used together through the example ruby_se.py
script. SPARC parallel applications work, and the timing *seems* right
from combined M5/Ruby debug traces. To run,
% build/ALPHA_SE/m5.debug configs/example/ruby_se.py -c

7311fd7182 ruby: Migrate all of ruby and slicc to SCons. 
Add the PROTOCOL sticky option sets the coherence protocol that slicc
will parse and therefore ruby will use.  This whole process was made
difficult by the fact that the set of files that are output by slicc
are not easily known ahead of time.  The easiest thing wound up being
to write a parser for slicc that would tell me.  Incidentally this
means we now have a slicc grammar written in python.

24da30e317 ruby: Make ruby #includes use full paths to the files they're including. 
This basically means changing all #include statements and changing

mem/protocol.

d8c592a05d ruby: remove unnecessary code. 
1) Removing files from the ruby build left some unresovled
symbols. Those have been fixed.

2) Most of the dependencies on Simics data types and the simics
interface files have been removed.

3) Almost all mention of opal is gone.

4) Huge chunks of LogTM are now gone.

5) Handling 1-4 left ~hundreds of unresolved references, which were
fixed, yielding a snowball effect (and the massive size of this
delta).

06b3e3c303 X86: Implement lowest priority interrupts more correctly. 
Lowest priority interrupts are now delivered based on a rotating offset into

it's much more likely that the group will stay consistent and the pain will be
distributed evenly.

88ab4bb257 X86: Make the local APICs register themselves with the IO APIC. 
This is a hack so that the IO APIC can figure out information about the local
APICs. The local APICs still have no way to find out about each other.
Ideally, when the local APICs update state that's relevant to somebody else,
they'd send an update to everyone. Without being able to do a broadcast, that
would still require knowing who else there is to notify. Other broadcasts are
implemented using assumptions that may not always be true.

c5e2cf841d X86: Record the initial APIC ID which identifies an APIC in M5.

6629d9b2bc mem: use single BadAddr responder per system. 
Previously there was one per bus, which caused some coherence problems
when more than one decided to respond.  Now there is just one on
the main memory bus.  The default bus responder on all other buses
is now the downstream cache's cpu_side port.  Caches no longer need
to do address range filtering; instead, we just have a simple flag
to prevent snoops from propagating to the I/O bus.

Daniel Sanchez
b0e9654f86 Commit m5threads package. 
This patch adds limited multithreading support in syscall-emulation
mode, by using the clone system call.  The clone system call works
for Alpha, SPARC and x86, and multithreaded applications run
correctly in Alpha and SPARC.

the store following an ldstl is automatically unlocking. We don't do it this
way for performance reasons since the behavior is the same.

d8a34a9745 mips-tlb-fix: check for alignment faults.\nMIPS was never updated to use TLBS correcty in SE mode. The error was forwarding translations directly to pageTable.

14808ecac9 o3, inorder: fix FS bug due to initializing ThreadState to Halted. 
For some reason o3 FS init() only called initCPU if the thread state
was Suspended, which was no longer the case.  There's no apparent
reason to check, so I whacked the test completely rather than
changing the check to Halted.
The inorder init() was also updated to be symmetric, though the
previous code was just a fancy no-op.

7617dcf736 ThreadState: initialize status to Halted in constructor. 
This provides a common initial status for all threads independent
of CPU model (unlike the prior situation where CPUs initialized
threads to inconsistent states).
This mostly matters for SE mode; in FS mode, ISA-specific startupCPU()
methods generally handle boot-time initialization of thread contexts
(since the right thing to do is ISA-dependent).

8882dc1283 Get rid of the Unallocated thread context state. 
Basically merge it in with Halted.
Also had to get rid of a few other functions that
called ThreadContext::deallocate(), including:
 - InOrderCPU's setThreadRescheduleCondition.
 - ThreadContext::exit().  This function was there to avoid terminating
   simulation when one thread out of a multi-thread workload exits, but we
   need to find a better (non-cpu-centric) way.

64ed39f61b pseudo inst: Add new wake cpu instruction for sending a message to wake a cpu. 
It's instantaneous and so it's somewhat bogus, but it's a first step.

f0fb3ac060 cpu: provide a wakeup mechanism that can be used to pull CPUs out of sleep. 
Make interrupts use the new wakeup method, and pull all of the interrupt
stuff into the cpu base class so that only the wakeup code needs to be updated.
I tried to make wakeup, wakeCPU, and the various other mechanisms for waking
and sleeping a little more sane, but I couldn't understand why the statistics
were changing the way they were.  Maybe we'll try again some day.

81180a3bf0 This fix addresses an ill formed if statement that fails 
to compile. The fix was the simple addition of another set
of parenthesis to ensure the correct condition resolution.
