QEMU uses it, but we already bundle the header files and update them
periodically from the files that Linux installs. So any change in Linux
would not break the QEMU build; having the header in UAPI is convenient
but I guess our update scripts could do whatever Linux's
scripts/headers_install.sh does.
That said, there are precedents in using UAPI this way for PV
interfaces. See for example include/uapi/linux/virtio*.h and
arch/x86/include/uapi/asm/kvm_para.h.
