[Qemu-devel] [PATCH v4 1/3] update-linux-headers.sh: add unistd.h and kvm on MIPS

["Michael S. Tsirkin" <mst@redhat.com>]

Rework the update script slightly, add the unistd.h header and its
dependencies on all architectures.

This also removes the IA64 and MIPS from a KVM blacklist:
Linux dropped IA64, and there was never a reason to
exclude MIPS from kvm specifically - it was
excluded due to dependency of its unistd.h on sgidefs.h,
which we also import.
