Hi All,
        These patches update the xm-test code to be more easily portable
to new architecture. This focus od this endevour is PPC but I believe
that IA64 also benifits.


By way of a quick status report.

With all thee patches applied to tip (7de08aceff6d) I ran:

I build xm-test:
cd xen.hg/tools/xm-test
INITRD="http://ozlabs.au.ibm.com/~tony/xm-test/"; make existing

I created a grouptest/xenppc file which contains most[1] of the
potential tests and pushed the whole xm-test dir (yes it's wasteful but
it's also easy) to my JS20 blade.  Then:
        ./runtest.sh -d -e [EMAIL PROTECTED] -g xenppc xenppc

creates the following report.
Xm-test execution summary:
  PASS:  48
  FAIL:  17
  XPASS: 0
  XFAIL: 0

Tony, this is so great!

You'd certainly expect the block-* tests to fail. I don't know why the
memset tests failed but I'll find out next week when I'm back at work.

xm mem-set does _not_ work because we have yet to implement "ballooning". We have not implemented ballooning YET, for a number reasons, off the top of my head: - Ballooning works by having a Linux driver allocate memory and have Xen release the packing pages - We cannot ever balloon the RMA, and Linux does not know how to allocate from non-RMA pages

There is also the reason of Domain memory allocations where we allocate memory in 16M sizes/aligned extents because Linux tryies to use 16M pages for the kernel linear mapping.

[1] I omitted create/destroy, save/restore, network* and the scheduler
tests becuase I know some of them crash the machine, attached is the
    xenppc file I used.

This is important, nothing should crash, only succeed or fail, these need to be attended to. I'm gonna start using this as my regression test, if anyone else does it would be great is we could file bugs and keep:

up to date.
