Normally, we only keep one patch or patch series from the same author that
modifies the same file in the review queue at a time.

You already have a patch for imx_rproc.c currently under review(got R-b, but
need Mathieu to handle), so this patch series might be delayed to be reviewed.

As I have replied in internal, to make multiple OS run on Cortex-A SMP without
hypervsior, some GIC changes are required, without those GIC changes,
this patchset is not testable using upstream tree.

Thanks,
Peng
