Subject: [GIT PULL] ARC updates for 4.7-rc1

Hi Linus,

We have a relatively big changeset for ARC for 4.7.

The highlight is support for EZChip (now Mellanox) NPS-400 network processor, a
400-Gb throughput C-programmable packet processor based on ARC700 cores from
Synopsys (http://www.mellanox.com/related-docs/prod_npu/PB_NPS-400.pdf)

Also present are irqchip and clocksource drivers for NPS as agreed with respective
maintainers to go via ARC tree due to an soc header dependency.
I have the needed ACKs from Jason, Marc, Daniel. You might run into a trivial
merge conflict in drivers/irqchip/*

This EZChip platform support required some deep changes in ARC architecture code
and also opportunity to cleanup past sins (legacy irq domains, missing irq domain
lookup, hard coded timer irqs...)

Please pull.

Thx,
-Vineet
