It really isn't a big speed difference. The context save/restore is minimal. The original thought was " ...well, I'm already here, I know we will take another exception, so may as well fake the error case and call do_page_fault." However, I really do like a minimal TLB miss case for valid PTEs, and push everything else to the heavyweight functions. Thanks. -- Dan
