Cool, next week :-). The current version works fine without. And I

Having returned from a 10-day weekend, I can only recommend this.
Hope you had fun and didn't read too much mail :-).
Yuck. What do we do? Implement set_bit_u64() and friends?
That's what I'd think we should do, yes.
For qemu I sent a patch that always uses "uint64_t" because that
works fine with the current code (32-bit on 64-bit uses the right
bytes for LE, 64-bit on 64-bit doesn't change). PPC is not
implement yet for anyone either and for now we only have dirty
logging with 64 bit kernels and 32-bit or 64-bit userspace, so
that's fine too.
As soon as someone implement dirty logging on a 32-bit big endian
target, it will break though, so before that day comes we need to
change set_bit to set_bit_64.
Perhaps we can get away with disabling 32-on-64 for the
configurations that break to start with.
32-on-64 only breaks for big endian which nobody except for this
target implements. Since my PPC enabling patches for qemu change the
type to uint64_t always, nobody is broken right now.
