c30b958988 Add fiq_installhandler(), so the current FIQ owner can change what handler 
they've got installed without relinquishing the FIQ.

0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

Reviewed by Jason.

7da5d70599 Add fiq_on() and fiq_off(), to enable and disable FIQs at the CPU. 
Call fiq_off() from start() and fiq_on() from cpu_configure(), so we're certain
not to get any FIQs during autoconfiguration.

35228f775a Two related changes: 
Make splhigh disable IRQs at the CPU rather than at the IOC.  This has the
potential to be faster, and more importantly ensures that splhigh() blocks
FIQ downgrades.

Have a variable which indicates that a FIQ downgrade is required, and ensure
that the IOC "force IRQ" bit is turned on in this case.  This ensures that
FIQ downgrades don't get lost if something happens to be fiddling with the
interrupt mask at the wrong moment.

45b5bdc5e5 Split off the pm_entries array from the rest of struct pmap. This makes 
memory allocation for it more efficient (since pm_entries is 4096 bytes long),
and will allow pm_entries to be freed for swapped processes.

9aa4896361 More FIQ support. This gives me enough to handle FIQs, and to downgrade them 
to IRQs as necessary.  All these interfaces are subject to change in the light

8b7128e398 Changes in aid of FIQ support: 
Add ioc_fiq_setmask().
  Change ioc_irq_status_full() to use the request registers rather than the
  status registers.  This is brings it into line with the Unix baclplane, and
  makes detecting downgraded FIQs possible.

ddf906b00d Use ld -N (OMAGIC), since this saves the 32k of RAM (by not putting a gap
