[PATCH 0/5] NPTL port to ARC

[Vineet Gupta]

Hi,

Please find the patches which bring NPTL to ARC.
These rely on TLS support in tools (gcc/binutils) which can be found at
specific branches on SNPS github site.

github.com:foss-for-synopsys-dwc-arc-processors/gcc.git:arc-4.8-tls
github.com:foss-for-synopsys-dwc-arc-processors/binutils.git:arc-2.23-tls

Arguably the 3 patches could be squashed into 1st (or 1st monolithic one
could be split into fine grained), I've kept them like that as they show
fixes needed on top of initial port. But I coudl merge them if reviewers
so wish.

Please review and consider merging.

Thx,
-Vineet
