The storage probe feature of the PS3 hypervisor returns device IDs. Add
the corresponding repository routine ps3_repository_find_device_by_id()
which can be used to retrieve the device info from the repository.

This adds hooks into the default_machine_crash_shutdown so drivers can
register a function to be run in the first kernel before we hand off
to the second kernel. This should only be used in exceptional
circumstances, like where the device can't be reset in the second
kernel alone (as is the case with eHEA). To emphasize this, the
number of handles allowed to be registered is currently #def to 1.
This uses the setjmp/longjmp code around the call out to the
registered hooks, so any bogus exceptions we encounter will hopefully
be recoverable.
Tested with bogus data and instruction exceptions.

smp_send_stop() will send an IPI to all other cpus to shut them down.
However, for the case of xmon-based reboots (as well as potentially some
panics), the other cpus are (or might be) spinning with interrupts off,
and won't take the IPI.
Current code will drop us into the debugger when the IPI fails, which
means we're in an infinite loop that we can't get out of without an
external reset of some sort.
Instead, make the smp_send_stop() IPI call path just print the warning
about being unable to send IPIs, but make it return so the rest of the
shutdown sequence can continue. It's not perfect, but the lesser of
two evils.
Also move the call_lock handling outside of smp_call_function_map so we
can avoid deadlocks in smp_send_stop().

The e500 MMU init code previously assumed KERNELBASE always equaled
PAGE_OFFSET and PHYSICAL_START was 0. This is useful for kdump
support as well as asymetric multicore.
For the initial kdump support the secondary kernel will run at 32M
but need access to all of memory so we bump the initial TLB up to
64M. This also matches with the forth coming ePAPR spec.

There were several issues if a memreserve range existed and happened
to be in highmem:
* The bootmem allocator is only aware of lowmem so calling
reserve_bootmem with a highmem address would cause a BUG_ON
* All highmem pages were provided to the buddy allocator
Added a lmb_is_reserved() api that we now use to determine if a highem
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.
