Subject: [GIT PULL] arch/arc updates for 3.11
Hi Linus,
First batch of ARC changes for 3.11. Please pull.
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.
Thx,
-Vineet

ARC: warn on improper stack unwind FDE entries (2013-06-27 14:37:59 +0530)
----------------------------------------------------------------
ARC changes for 3.11
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
