Description Markus Armbruster 2007-11-27 16:58:09 UTC 
Description of problem:
Rebasing the HV to 3.1.2 brings in the hypervisor part of Xenoprof backtrace
support (xen-3.1-testing.hg cset 15157:76bde58ffeac).  The kernel part is in
linux-2.6.18-xen.hg csets 36 and 37.  Diffstat:

 drivers/xen/xenoprof/xenoprofile.c |  102 ++++++++++++++++++++++++++-----------
 include/xen/interface/xenoprof.h   |    8 ++
 2 files changed, 80 insertions(+), 30 deletions(-)

The header is public, so we need to be extra careful there.  The change adds
three macros, and bumps the value of macro XENOPROF_last_op from 14 to 15.  I
figure that's safe, but we better make sure.

I figure not taking these patches won't break anything.  Taking them gives us
backtrace support, which would be nice to have.
