better mysql error messages
base/stats/mysql.cc:
better placement of commit() calls to avoid failing transactions
due to what I think are timeouts.

are more efficient and reduce the number of new/delete calls
arch/alpha/stacktrace.cc:
- Change the StackTrace code so that the class can more easily be
cleaned out and reused to avoid extra allocations.
- Allow trace() to accept a static instruction pointer so it can
determine if the instruction is worth tracing. This is moved from
the CPU.
- provide constants for special meaning PCs (user, console, unknown),
instead of magic numbers
- switch to using kernelSymtab instead of allSymtab which will be
going away
- if the stack adjustment doesn't make any sense, exit and push
unknown so we don't get into an infinite loop or record garbage.
- check to see if we've made too many iterations through the stack
and panic to avoid an infinite loop

cpu/base.cc:
only clear the profile if we have one
include profile.hh here since base.hh doesn't do it anymore
cpu/base.hh:
no need to include cpu/profile.hh here
cpu/profile.cc:
use ProfileNode pointers instead of objects in the ChildList
Consume a vector of addresses since that's really all we
care about.
cpu/profile.hh:
Keep pointers to ProfileNodes to reduce the size of these structures
keep a StackTrace around so that we may reuse it.
provide consume functions that use the new StackTrace trace interface
one consume function is inline and tries to fastpath the no trace
condition, it calls the outlined consume function if a trace is generated.
cpu/simple/cpu.cc:
include cpu/profile.hh here since base.hh no longer does
use the new FunctionProfile::consume interface
(which contains the tracing functions)

call it when value is updated (not just in constructor)

interrupts.
dev/sinic.cc:
- The prepareRead function sets all the variables in the register
file that depend on various state bits that change on the fly.
Includes RxDone, RxWait, TxDone, and TxWait
- Use the new register information accessor functions to grab
validity and size information for the read and write functions
- read all registers directly from the register space by offset
and size, not by actual name (less code)
- The side effect of reading the interrupt status (clearing it) now
happens outside the actual chunk of code where the value is loaded.
- Add an iprRead function for when we may want speculative access
to device registers through an ipr or special instruction.
- When RxData or TxData are written, their busy flag is set to
indicate that they have an outstanding transaction.
- The RxHigh and TxLow interrupts are special, they only interrupt
if the rxEmpty or txFull limits were hit
- Move reset to the command register
- Update more registers on reset, clear rxEmpty and txFull
- Data dumps only happen if EthernetData trace flag set
- When a DMA completes, kick the other engine if it was waiting
- implement all of the new interrupts
- serialize the new stuff
dev/sinic.hh:
- Put all registers with their proper size and alignment into
the regs struct so that we can copy multiple at a time.
- Provide accessor functions for accessing the registers with
different sizes.
- Flags to track when the rx fifo hit empty and the tx fifo became
full. These flags are used to determine what to do when below
the watermarks, and are reset when crossing the watermark.
- the txDmaEvent should actually trigger the txDmaDone function
- Add an iprRead function for when we may want speculative access
to device registers through an ipr or special instruction.
- The prepareRead function sets all the variables in the register
file that depend on various state bits that change on the fly.
- add rx_max_intr and dedicated (for dedicated thread) config params
dev/sinicreg.hh:
Add some new registers: Command, RxMaxIntr, RxFifoSize, TxFifoSize,
rename XxThreshold to XxFifoMark
Move Reset to the Command register
Add Thread to the Config register
New interrupts, better names
More info in RxDone and TxDone
Easier access to information on each register (size, read, write, name)
python/m5/objects/Ethernet.py:

Add a parameter to configure the maximum number for receive
