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.
