Hi Linus !

Here is some powerpc goodness for -rc2. Arguably -rc1 material more than
-rc2 but I was travelling (again !)

It's mostly bug fixes including regressions, but there are a couple of
new things that I decided to drop-in.

One is a straightforward patch from Michael to add a bunch of P8 cache
events to perf.

The other one is a patch by myself to add the direct DMA (iommu bypass)
for PCIe on Power8 for 64-bit capable devices. This has been around for
a while, I had lost track of it. However it's been in our internal
kernels we use for testing P8 already and it affects only P8 related
code. Since P8 is still unreleased the risk is pretty much nil at this
point.

Cheers,
Ben.
