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.
