Merge tag 'arc-v3.11-rc1-part1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull first batch of ARC changes from Vineet Gupta:
"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.
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"
