Subject: [PATCH 0/8] MIPS: Aggregate build fixes

Hi all,

This series is a collection of build fixes that have been lying
at my local trees for a while, some of them are for Clang built
linux and others are for some wiredo configurations.

Please review.

Thanks

Subject: [PATCH 2/8] MIPS: Remove cc-option checks for -march=octeon

Nowadays our minimal supported GCC/Clang all support -march=octeon.
Remove cc-option checks to simplify code.
