[PATCH] time initialisation fix

We're not reay to take a timer interrupt until timekeeping_init() has run.
But time_init() will start the time interrupt and if it is called with
local interrupts enabled we'll immediately take an interrupt and die.

Fix that by running timekeeping_init() prior to time_init().

We don't know _why_ local interrupts got enabled on Jesse Brandeburg's
machine.  That's a separate as-yet-unsolved problem.  THe patch adds a little
bit of debugging to detect that.

This whole requirement that local interrupts be held off during early boot
keeps on biting us.
