As we rebase this code base onto 3.10-rcX and start upstreaming, can we make IKS a topic branch to be added to the LLCT tree? That way Andrey (cc'ed) could pull this in for 13.05 and you won't have to maintain two separate IKS+MP branches. To be perfectly clear, LLCT's 'linux-linaro' branch would then contain IKS + ARM's reference MP patchset. Viresh and Vincent would then create another tree that would take linux-linaro, revert the reference MP patchset and apply the upstream-friendly version of the MP patchset. > This code was also developed for and tested on the VExpress TC2 > development platform.
