Keir,
I am trying to debug the SMP dom0 boot issue on x86_64. I find the
changeset 7402 is breaking SMP.
Your patch 7402: ba9706473941520247153e7e31d89899285d09ce is
extending the event-channel pending and mask arrays to longs.
I think the synch_const_test_bit should also change accordingly. This
does not fix the SMP issue yet, but is this the right way to fix it?
sync_const_test_bit does not need to change. Note it casts the bitmap
pointer to 'int' which is 32-bit quantity even on x86/64. So we do want
to divide the offset by 32, not BITS_PER_LONG.
