address width is greater than 32 bits.

Add support to the ramdump parser to parse debug image v2
format. Current support is for parsing cpu context and QDSS
dumps.

We don't support python3 at all and python2.6 can only be used if the
user installs an extra package (OrderedDict [1]). Ask for python2
explicitly in the shebang line to resolve the python3 issues and print
some instructions to the user regarding python2.6 when that is used.

If the user insists on using python2.6, provide a command line
switch (--force-26) to skip the version check. To reduce clutter, don't
document this switch in the --help text but inform the user about its
existence when we error out due to the python2.6 check.

In order to even print an error message in python3 we have to first
ensure that our code is valid in python3, otherwise the interpreter
fails to even start executing our code (so we can't print any
messages). Use 2to3 to patch up some print statements, etc. Also fix
inconsistent whitespace, which is a syntax error on python3.

ListWalker.__init__ was recently changed to remove some unneeded
arguments. The vmalloc parser was also updated at roughly the same time
with a new usage of the ListWalker class and was using the old
constructor. Update it.

It's not always useful to pass extra data to the list walker function.
For example, if the list walker function is a class method, state can be
passed around by simply modifying class instance variables. Update
`ListWalker.walk' to accept extra arguments optionally, not require
them.

The parser now requires Python 2.7 so that 2.7-specific features can be
leveraged. Update the README to reflect this.

[29d3f2ed: "lrdp-v2: refactor Iommu domain parsing code"] introduced
an extra argument for rb_tree `walker' functions, but didn't update the
runqueue rb_tree user, so the ramdump parser currently fails to print
the runqueue state. Fix this.

For certain dumps, before this change we would see the following
backtrace:

Because pages are constantly being allocated and freed, the pagetypeinfo
may not be in a consistent state when dumps are collected. Check
to make sure there are no cycles in the list for more than just the
next item.

It's bothersome at a fundamental level that the first line of the
stack trace is printed out on the same line as the 'Stack:' tag.
Fix it.

The number of interrupts is an int which is different from the word
size. Switch to it.

The way the vmalloc list is walked has changed to use a different
structure. The old structure is now freed at init time. This may
not be noticed if init memory isn't freed. Switch to a method that
does not rely on not freeing initmem.

Many of the lists are very large and may overflow if traversed
recursively. Switch to an iterative method instead.

Currently, if the user doesn't specify a vmlinux image or an
autodumpdir (like when running ramparse.py with absolutely no arguments)
they get a big ugly python stacktrace and no helpful error message. Fix
this.

The IOMMU parser currently only supports short-descriptor format page
tables but hardware supports long-descriptor format page tables. Add
support for the long-descriptor format. Most of the existing LPAE MMU
code can be re-used for this, although it must be refactored a bit.
