* The bootmem allocator is only aware of lowmem so calling
  reserve_bootmem with a highmem address would cause a BUG_ON

page should continue to be PageReserved or provided to the buddy
allocator.

Also, we incorrectly reported the amount of pages reserved since all
highmem pages are initally marked reserved and we clear the
PageReserved flag as we "free" up the highmem pages.

The device tree contains a property "nmi-source" in the openpic node

Also, for these interrupts, the IACK is read from another register than
the regular (MCACK instead), but they are EOI'd as usual. So implement
said function for the mpic driver.

[POWERPC] 4xx: make UIC use generic level irq handler

This patch makes PowerPC 4xx UIC use generic level irq handler instead
of a custom handle_uic_irq() function. We ack only edge irqs in mask_ack
callback, since acking a level irq on UIC has no effect if the interrupt
is still asserted by the device, even if the interrupt is already masked.
So, to really de-assert the interrupt we need to de-assert the external
source first *and* ack it on UIC then. The handle_level_irq() function
masks and ack's the interrupt with mask_ack callback prior to calling
the actual ISR and unmasks it at the end. So, to use it with UIC interrupts
we need to ack level irqs in the unmask callback instead, after the ISR
has de-asserted the external interrupt source. Even if we ack the interrupt
that we didn't handle (unmask/ack it at the end of the handler, while
next irq is already pending) it will not de-assert the irq, untill we
de-assert its exteral source.
