So, the build is still in progress but I'm seeing a handful of errors
related to MACH_TYPE_xxx values that are not present in v4.9.  In fact
(at first glance) appear to have been removed in various re-syncs with
the official source of the list.  I'm probably going to re-work this as
a series to remove the CONFIG_MACH_TYPE usage from a number of platforms
and then re-sync.
