Given that you know you're going to call this at least 8 times in a row,
probably with all operations on the same page, it is worth querying the qemu
tlb first, and when that fails but the lookup succeeds, installing the result
into the tlb?
I know we don't have a primitive for that within exec/cputlb.h, but perhaps we
should. Perhaps a more generic form of probe_write...
That said, this isn't wrong so
