[Qemu-devel] [PULL 09/28] update-linux-headers.sh: unistd.h, kvm consist

From: Michael S. Tsirkin
Subject: [Qemu-devel] [PULL 09/28] update-linux-headers.sh: unistd.h, kvm consistency
Date: Wed, 23 May 2018 17:43:02 +0300

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.
