Hi Linus !

Here's the powerpc batch for this merge window.

Most of it is in arch/powerpc, a few powerpc specific drivers are hit
too, including removing one that has been unused (and unselectable in
Kconfig) for a long time (hdpuftrs), probably remains of a long dead
platform.

This time around, there's a lot of bits and pieces left and right, no
huge highlight. Some notable fixes to kexec/kdump that might make this
thing finally somewhat reliable from Mikey and Anton and a big cpumask
conversion from Anton as well.

Cheers,
Ben.
