214cc0fafc inorder: get rid of references to mainEventQueue.
Events need to be scheduled on the queue assigned
to the SimObject, not on the global queue (which
should be going away).
Also cleaned up a number of redundant expressions
that made the code unnecessarily verbose.

5e0b8337ed inorder: add/remove halt/deallocate context respectively
Halt is called from the exit() system call while
deallocate is unused. So to clear up things, just
use halt and remove deallocate.

aacc5cb205 inorder: add updatePC event to resPool
this will be used for when a thread comes back from a cache miss, it needs to update the PCs
because the inst might of been a branch or delayslot in which the next PC isnt always
a straight addition

4dbc2f1718 inorder: suspend in respool
give resources their own specific
activity to do for a "suspend" event
instead of defaulting to deactivating the thread for a
suspend thread event. This really matters
for the fetch sequence unit which wants to remove the
thread from fetching while other units want to
ignore a thread suspension. If you deactivate a thread
in a resource then you may lose some of the allotted
bandwidth that the thread is taking up...

e1fcc64980 inorder: activate thread on cache miss
-Support ability to activate next ready thread after a cache miss
through the activateNextReadyContext/Thread() functions
-To support this a "readyList" of thread ids is added
-After a cache miss, thread will suspend and then call
activitynextreadythread

eac5eac67a inorder: squash on memory stall
add code to recognize memory stalls in resources and the pipeline as well
as squash a thread if there is a stall and we are in the switch on cache miss

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.

3a057bdbb1 inorder-tlb: squash insts in TLB correctly
TLB had a bug where if it was stalled and waiting , it would not squash all instructions older than squashed instruction correctly

1c8dfd9254 inorder-alpha-port: initial inorder support of ALPHA
Edit AlphaISA to support the inorder model. Mostly alternate constructor functions and also a few skeleton multithreaded support functions
* * *
Remove namespace from header file. Causes compiler issues that are hard to find
* * *
Separate the TLB from the CPU and allow it to live in the TLBUnit resource. Give CPU accessor functions for access and also bind at construction time
* * *
Expose memory access size and flags through instruction object
(temporarily memAccSize and memFlags to get TLB stuff working.)

973d8b8b13 InOrder: Import new inorder CPU model from MIPS.
This model currently only works in MIPS_SE mode, so it will take some effort
to clean it up and make it generally useful. Hopefully people are willing to
help make that happen!
