Hi,

Here is a port of KVM-trace, currently using macros on top of the Linux Markers,
to tracepoints. Note that I cleaned up the instrumentation too, so stuff like

KVMTRACE_3D(CR_WRITE, vcpu, (u32)cr,
(u32)kvm_register_read(vcpu, reg),
(u32)((u64)kvm_register_read(vcpu, reg) >> 32),
handler);

Sprinkled all across the KVM C code becomes :

trace_kvm_cr_write(vcpu, cr, reg);

Which looks much nicer, IMHO.

It applies on top of linux-next patch-v2.6.26-next-20080715.
