Highlights of changes:
-Continuation of ARC MM changes from 3.10 including
zero page optimization;
Setting pagecache pages dirty by default;
Non executable stack by default;
Reducing dcache flushes for aliasing VIPT config
-Long overdue rework of pt_regs machinery - removing the unused word gutters
and adding ECR register to baseline (helps cleanup lot of low level code)
-Support for ARC gcc 4.8
-Few other preventive fixes, cosmetics, usage of Kconfig helper..
The diffstat is larger than normal primarily because of arcregs.h header split
as well as beautification of macros in entry.h

"There's a second bunch to follow next week - which depends on commits
on other trees (irq/net). I'd have preferred the accompanying ARC
change via respective trees, but it didn't workout somehow.
