It turns out that we have unistd.h and kvm headers for some
architectures but not others.  We are thus unable to use e.g. usefaultfd
on these systems unless system headers have been updated.

Fix up update-linux-headers.sh to make sure we auto-updates
all architectures which have linux-headers/
(unfortunately this still does not mean "all linux systems").

Tested on x86 only.

Pls consider merging this through the ARM tree.

changes from v4:
    dropped s390 chunks - already upstream

Michael S. Tsirkin (3):
  update-linux-headers.sh: unistd.h, kvm consistency
  linux-headers: add unistd.h on all arches
  linux-headers: add kvm header for mips

Hi. Patch 1 doesn't seem to apply to current master -- could you
rebase and resend, please?

thanks

Done, v6 posted.
