Subject: [GIT PULL] ARC updates for 4.2-rc1
Hi Linus,
I'm pleased to send this pull request which among others contains Linux port to
HS38x cores based on new ARCv2 ISA from Synopsys.
We've been working on this for more than a year now and it feels good to hand it
over now.
Some of the patches have been reviewed by experts: Peter and Will commented on the
barriers stuff and were reworked to same effect.
P.S. There's trivial merge conflict in include/asm-generic/barrier.h (patch has
been Acked by Peter already)
Please Pull !
Thx,
-Vineet

ARC: Fix build failures for ARCompact in linux-next after ARCv2 support
(2015-06-28 20:30:13 +0530)
----------------------------------------------------------------
- Support for HS38 cores based on ARCv2 ISA
ARCv2 is the next generation ISA from Synopsys and basis for the
HS3{4,6,8} families of processors which retain the traditional ARC mantra of
low power and configurability and are now more performant and feature rich.
HS38x is a 10 stage pipeline core which supports MMU (with huge pages) and
SMP (upto 4 cores) among other features.
