[PATCH v2 14/15][KVMTOOL] update_headers: Sync kvm UAPI headers with linux v5.2-rc1

Sudeep Holla
2019-05-23T10:36:00Z

The local copies of the kvm user API headers are getting stale.

In preparation for some arch-specific updated, this patch reflects
a re-run of util/update_headers.sh to pull in upstream updates from
linux v5.2-rc1.
