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.
