@@ -1980,6 +1980,7 @@ static int do_swap_page(struct mm_struct } flush_icache_page(vma, page); + lazy_mmu_prot_update(pte); set_pte_at(mm, address, page_table, pte); page_add_anon_rmap(page, vma, address);
At first sight, this looks redundant ... but then I saw that on ia64 "flush_icache_page()" is actually a no-op. Perhaps we can enter this in the next obfuscated C competition.
