>From Nico's reply to his pull request of vmalloc cleanup series, it
looks like that pull request has been withdrawn (hope I am not missing
anything here). Without Nico's series, and gic dt support for exynos4
support requiring this patch, all other workarounds to replace this
patch does not seem be correct.

So is it acceptable to retain this patch and later rework/drop the
exynos4 specific ioremap along with Nico's vmalloc patch series when
it is merged.

Thanks,
Thomas.
