Hi Marek,
With v19, I can't seem to allocate big regions anymore (e.g. 101MiB).
In particular, this seems to fail:

The above WARN_ON_ONCE is triggered, and then the conditional is
asserted (page_zone() retuns a "Movable" zone, whereas zone is
"Normal") and the function fails.
This happens to me on OMAP4 with your 3.3-rc1-cma-v19 branch (and a
bunch of remoteproc/rpmsg patches).
Do big allocations work for you ?
