Pages allocated with GFP_KERNEL cannot come from Highmem. That is why there is no need to call kmap() on them. Therefore, don't call kmap() on the page coming from vma_res->bi.pages using for_each_sgt_page() in i915_vma_coredump_create(). Use a plain page_address() to get the kernel address instead.
