Or supply an alternative patch to config it back? I'm staggered. We do want to be able to have pte pages in highmem. I would rather just have it always enabled if CONFIG_HIGHMEM=y, rather than putting the config option back. I think that should just involve adding __GFP_HIGHMEM to the flags for alloc_pages in pte_alloc_one unconditionally, no?
