Merge tag 'arc-4.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC updates from Vineet Gupta:
- Support for new MM features in ARCv2 cores (THP, PAE40) Some generic
THP bits are touched - all ACKed by Kirill
- Platform framework updates to prepare for EZChip arrival (still in works)
- ARC Public Mailing list setup finally (linux-snps-arc@lists.infraded.org)
