[PATCH kernel 0/9] powerpc/kvm/vfio: Enable in-kernel acceleration

[Alexey Kardashevskiy <aik@ozlabs.ru>]

This is my current queue of patches to add acceleration of TCE
updates in KVM.

This is based on the "next" branch of
git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git

I am not doing changelog here as it is 4 months since last respin
and I am sure everybody lost the context anyway, I tried to be
as detailed as I could in the very last patch, others are
pretty trivial anyway.

Please comment. Thanks.
