__user macro does not appear in exported headers
and should not be in headers qemu-kvm includes.

Huh?
Doesnt that create a sparse warning? You already mention that the exported
header does not contain __user and that is perfectly ok:
- for the kernel dirty_bitmap is in the user address space, so we need the __user
- userspace does not know and need the __user so it is removed during
headers_install.

This is in the copy of the headers that qemu-kvm.git carries, not the
kernel master.
