Hi
If you see my RAMState series, you can see that things have moved a lot
here, I added this to my current series:
(there is a rename of qemu_target_page_bits() to qemu_target_page_size()
in the series).
If you like it, I can leave it that way there.
Thanks, Juan.

Add page-size to output in 'info migrate'
The number of dirty pages outputed in 'pages' in the command
'info migrate', so add page-size to calculate the number of dirty
pages in bytes.
