Thanks to suzuki.poulose@arm.com for the review comments.

bwicaksono@nvidia.com/

These patches no longer apply. Please can you rebase onto -rc4 and drop the
defconfig change from the first patch?

Why does the defconfig change need to be dropped ?

Oh, just because that file is a big source of conflicts so I'd prefer to
keep defconfig changes separate from patches which add new functionality.

Will
