mm/highmem: fix __kmap_to_page() build error
[ Upstream commit 94350fe6cad77b46c3dcb8c96543bef7647efbc0 ]
This changes fixes following build error which is a miss from ef6e06b2ef87
("highmem: fix kmap_to_page() for kmap_local_page() addresses").
mm/highmem.c:184:66: error: 'pteval' undeclared (first use in this
function); did you mean 'pte_val'?
184 | idx = arch_kmap_local_map_idx(i, pte_pfn(pteval));
In __kmap_to_page(), pteval is used but does not exist in the function.
(akpm: affects xtensa only)
