hello, The implementation of pte_offset_map() for ppc assumes that PTEs are kept in highmem (CONFIG_HIGHPTE). There is only one implmentation of pte_offset_map() as follows (include/asm-ppc/pgtable.h):
#define pte_offset_map(dir, addr) \ ((pte_t *) kmap_atomic(pmd_page(*(dir)), KM_PTE0) + pte_index(addr)) Shouldn't this be made conditional according to CONFIG_HIGHPTE is defined or not (as implemented in include/asm-i386/pgtable.h) ? the same goes for pte_offset_map_nested and the corresponding unmap functions. thanks, Satya Popuri _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
