This ensures that we don't get a decrementer interrupt arriving before
we have set up a handler for it.

Maybe add a comment saying this is setting MSR[EE]=0 for that?  Or do
other bits here matter as well?

Hmm, it actually clears MSR[RI] as well.

__hard_irq_disable() is what we want here, unless the MSR[RI] clearing 
is required as well, in which case there is __hard_EE_RI_disable().

But neither of those exist in the boot wrapper (yet).

cheers
