This is the second patchset needed to support THP on ppc64. Some of the changes
included in this series are tricky in that it changes the powerpc linux page table
walk subtly. We also overload few of the pte flags for ptes at PMD level (huge
page PTEs).

The related mm/ changes are already merged to Andrew's -mm tree.

If I am to put that into powerpc-next, I need the dependent mm/ changes as well.

Do you have them in the form of a separate git tree that is *exactly* (same SHA1s)
what is expected to go upstream via Andrew ?

Andrew, are they fully acked on your side and ready to go ?

Not being on linuxppc-dev I'm at a bit of a loss here.

I assume we're referring to

mm-thp-add-pmd-args-to-pgtable-deposit-and-withdraw-apis.patch
mm-thp-withdraw-the-pgtable-after-pmdp-related-operations.patch
mm-thp-withdraw-the-pgtable-after-pmdp-related-operations-fix.patch
mm-thp-dont-use-hpage_shift-in-transparent-hugepage-code.patch
mm-thp-deposit-the-transpare-huge-pgtable-before-set_pmd.patch

?

Yes, they're ready to go.  I'll squirt them over at you and will drop
my copies when I see them turn up in linux-next.
