  Hi,

This is a pile of miscll improvements/updates sitting in one of my local trees.
Given the recent warning fix, we coudl also push them out.
@Alexey, @Shahab: care to give these a spin on hsdk (and test ARC700 build/boot on nSIM if possible).

Thx,
-Vineet

The entire "ARC updates" patch series (with all subsequent patches with updates)
has been tested on the HSDK borard for ARCv2 using the glibc and ksefltest test 
framworks and on nSIM for ARCompact using the uclibc tests. No regressions found.

Tested-by: Pavel Kozlov <Pavel.Kozlov@synopsys.com>
