I am wondering why you need the separate cpu and head variables. I
thought one will be enough here. The wait code put the cpu number in
head, the the kick_cpu code kick the one in cpu which is just the cpu #
of the tail.

I think it is better to use a constant like -2 for NO_HEAD instead of an
external variable.

[PATCH 00/11] qspinlock with paravirt support
Since Waiman seems incapable of doing simple things; here's my take on the
paravirt crap.
The first few patches are taken from Waiman's latest series, but the virt
support is completely new. Its primary aim is to not mess up the native code.
I've not stress tested it, but the virt and paravirt (kvm) cases boot on simple
smp guests. I've not done Xen, but the patch should be
