Miller" Errors-To: linuxppc-dev-bounces+linuxppc-dev=archiver.kernel.org@lists.ozlabs.org Sender: "Linuxppc-dev" The original PowerPC highmem mapping function used __set_pte_at() to denote that the mapping is per CPU. This got lost with the conversion to the generic implementation. Override the default map function.
