Some HW platforms, such as the new cell blades, requires some MPIC sources
to be left alone by the operating system. This implements support for
a "protected-sources" property in the mpic controller node containing a list
of source numbers to be protected against operating system interference.
For those interested in the gory details, the MPIC on the southbridge of
those blades has some of the processor outputs routed to the cell, and
at least one routed as a GPIO to the service processor. It will be used
in the GA product for routing some of the southbridge error interrupts
to the service processor which implements some of the RAS stuff, such
as checkstopping when fatal errors occurs before they can propagate.

Classic 32-bit PowerPC CPUs, and the early 64-bit PowerPC CPUs, don't
provide a way to prevent execution from readable pages, that is, the
MMU doesn't distinguish between data reads and instruction reads,
although a different exception is taken for faults in data accesses
and instruction accesses.
Commit 9ba4ace39f, in the course of
fixing another bug, added a check that meant that a page fault due
to an instruction access would fail if the vma did not have the
VM_EXEC flag set. This gives an inconsistent enforcement on these
CPUs of the no-execute status of the vma (since reading from the page
is sufficient to allow subsequent execution from it), and causes old
versions of ppc32 glibc (2.2 and earlier) to fail, since they rely
on executing the word before the GOT but don't have it marked
executable.
This fixes the problem by allowing execution from readable (or writable)
areas on CPUs which do not provide separate control over data and
instruction reads.

Move firmware feature initialisation from pSeries_init_early to the
earlier pSeries_probe_hypertas so they are initialised before firmware
feature fixups are applied.
Currently firmware feature sections are only used for iSeries which
initialises the these features much earlier. This is a bug in waiting
on pSeries.
Also adds some whitespace fixups.

In the future some drivers may need to use ACPI to determine the low power
states in which to place their devices, but to provide the drivers with this
information the ACPI core needs to know what sleep state the system is going to
enter. Namely, the device's state should not be too high power for given system
sleep state and, if the device is supposed to be able to wake up the system, its
state should not be too low power for the wake up to be possible). For this
purpose, the ACPI core needs to implement the set_target() method in 'struct
pm_ops' and store the target system sleep state passed by the PM core in a
variable.

and the contents are the binary table image.
Some tables, such as the SSDT, can have multiple instances.
If just one, the file is SSDT, but if 3 instances,
for example, it will be SSDT1, SSDT2, SSDT3
All static tables (besides teh RSDP and RSDT themselves

are not declared in the RSDT, will be added in a subsequent patch.

Split ACPI_DEBUG into function trace enabled and not enabled.
Function trace is most of the ACPI_DEBUG costs, but is
not much of use for kernel ACPI debugging.
Size of kernel image increased on test compile:
+ 48k (Full ACPI_DEBUG)
+ 35k (ACPI_DEBUG with function trace compiled out)
Performance without function trace is also much better.
Also remove ACPI_LV_DEBUG_OBJECT from default debug level as
a lot vendors let Store (value, debug) in their code and this
might confuse users when it pops up in syslog.
