[GIT PULL] arch/arc for 3.10

[GIT PULL] arch/arc for 3.10

[Vineet Gupta]

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
