This patch breaks QEMU build when doing a 'make sync'. When you do a
top-level ./configure, libkvm is built with kerneldir pointing to
kvm-userspace/kernel/include. While linux/kvm.h is present there, there
isn't a linux/compiler.h.
The host kernelpath isn't normally part of the libkvm or QEMU build. So
we have a couple options.
1) make the host kernelpath (/lib/modules/$(uname -r)/build/include)
part of the libkvm/QEMU build.
2) Do something else about __user
Suggestions? #1 might be a pain since there may be include conflicts
between the host kernel include and kernel/include.
