This is my feeble attempt to port xenoprof to xen-unstable. I really
did not make a lot of changes, but(!) the one big caveat is that it
does not work :)
The 2 patches attached are for ./xen and for ./linux-2.6.11-xen-sparse.
Both should patch cleanly against bk (2005-04-15) and should compile
fine. It does boot, but starting profiling causes xen to stop (output
below).
I'm not sure if this is of any use to anyone (being that it does not
work yet), but I'd thought "why not" and maybe someone with more
knowledge would point out some obvious errors I made.
