there is one small thing apart of the issue Stephen noticed, barrier()
between the two 32-bit writes should IMO be

I dislike the "__HAVE_ARCH_xxx" approach, and considering that most
architectures will probably want to do something specific anyway I
wonder if we should get rid of that and just make

Below is take two of the patch making pte_clear use atomic xchg in an
effort to avoid the loss of dirty bits. PAE no longer uses cmpxchg8 for
updates; set_pte is two ordered long writes with a barrier. The use of
long long for ptes is also removed; gcc should generate better code
