Revision 63b9b80e9f5b2c463d98d6e550e0d0e3ace66033 authored by Michael S. Tsirkin on 19 November 2019, 10:25:24 UTC, committed by Michael S. Tsirkin on 11 December 2019, 13:14:07 UTC
We managed to get confused about the shift direction at least once. Let's switch to division/multiplcation instead. Add a number of pages macro for this purpose. We still keep the order macro around too since this is what alloc/free pages want. Signed-off-by: Michael S.
