for_each_cpu() actually iterates across all possible CPUs. We've had mistakes
in the past where people were using for_each_cpu() where they should have been
iterating across only online or present CPUs. This is inefficient and
possibly buggy.
We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the
future.
This patch replaces for_each_cpu with for_each_possible_cpu.

I'm not sure where the information came from, but I assumed
that doing cache-inhibited mappings for mmio regions was
sufficient.
It seems we also need the guarded bit set, like everyone
else, which is the default for ioremap.

These symbols are only used in the file that they are defined in,
so they should not be in the global namespace.

This patch enables support for pause(0) power management state
for the Cell Broadband Processor, which is import for power efficient
operation. The pervasive infrastructure will in the future enable
us to introduce more functionality specific to the Cell's
pervasive unit.
