Sorry for the confusion on my part. I was aware of the sanitized
kernel headers, but was mislead by the line
kerneldir=/lib/modules/$(uname -r)/build
in kvm/user/configure. What I didn't realize is that this
always gets overridden by kvm/configure.
Maybe we can change the default in kvm/user/configure to
something more sensible:
---
[PATCH] kvm: user: fix default kerneldir
calling ./configure in kvm/user sets the kerneldir to the
currently running kernel, which is incorrect for user code.
This changes the default to the sanitized header files from
the kvm/kernel directory.

I usually add a readlink -f in there due to my innate fear of relative
directories and cd.
btw, these are my plans for kvm/user:
- convert the tests to be loadable with qemu -kernel; we lose the
simplicity of kvmctl so I'm not 100% sure it's a good idea. On the
other hand some of the tests are useful for tcg.
- kill kvmtrace (replaced by the standard ftrace tools, whatever they
are; maybe create a new repo if kvm specific tools are needed)
