OK this is no blocker, and do proceed with this as the kernel sure
looks better after this than before it.

However as the next step I would prefer that we start to get rid of
all the NEED_MACH_FOO_H used for just refactoring out headers.

Can we not completely do away with this header next, and provide
the services it supplied locally in the mach-foo folder for these machines
instead so we do not need to have all these Kconfig things and preserve
the <mach/*> namespace for them?

The real trick is to make CLOCK_TICK_RATE and LATCH runtime
variables instead of a compile-time variables, right? Can't we do
this?

Yours,
