[GIT PULL] arch/arc for 3.10
From: Vineet Gupta
Date: Thu May 09 2013 - 00:52:31 EST
Hi Linus,
Please consider pulling ARC changes for 3.10 (shortlog below).
Note that the base-point is not a well known 3.9-rcX because of the PREEMPT_COUNT
+ compiler barrier fiasco - and I didn't bother to rebase after that. However the
series applies cleanly on top your tree as of today.
Also, I'm in the final stages of testing the d-cache aliasing support, so those
would follow in a day or two.
Thanks,
Vineet

ARC: [mm] Lazy D-cache flush (non aliasing VIPT) (2013-05-07 19:08:15 +0530)
----------------------------------------------------------------
ARC port updates for Linux 3.10 (part 1)
* Support for two new platforms based on ARC700
- Abilis TB10x SoC [Chritisian/Pierrick]
- Simulator only System-C Model [Mischa]
* ARC specific MM improvements
- Avoid full TLB flush (ASID increment) on munmap (even single page)
- VIPT Cache Flushing improvements
+ Delayed dcache flush for non-aliasing dcache (big performance boost)
+ icache flush aliasing agnostic (no need to kill all possible aliases)
* Others
- Avoid needless rebuild of DTB files for every kernel build
- Remove builtin cmdline as that is already provided by DeviceTree/bootargs
- Fixing unaligned access emulation corner case
- checkpatch fixes [Sachin]
- Various fixlets [Noam]
- Minor build failures/cleanups
