I guess that there is a good reason for changing for an array of ints to
one bitmap.
Change looks ok, and if it worked for you, it should work for everybody
(if you breaks pci_device migration stops working).
I would delay changing things to bitmaps until we decide how to
implement bitmaps in qemu (there are more than one implementation), at
least:
- use array of ints, save as array of ints (i.e. works between hosts with
different endianess)
- use arraf of ints but save as array of bytes (break when you change
endianess)
- Now, you have a bitmap that fits in an uint8_t.
An probably some other way that I have missed.
Later, Juan.
