Xen devel - Oct 2006 - [PATCH] Fix balloon driver for auto_translated_physmap guests

For guest domains running in auto_translated mode, the domain builder
maps the guest grant table at the end of its physmap, i.e. from page
frame ''nr_pages'' to page frame ''nr_pages +
NR_GRANT_FRAMES''.

However, the balloon driver, on initialization, appends all page frames
from ''nr_pages'' to ''max_pfn'' to its
ballooned_pages list (this includes
the grant table page frames). This ballooned_pages list is subsequently
used for increasing memory reservation. 

Thus for auto_translated guests, the balloon driver remaps the grant
table page frames when it tries to increase the memory reservation.

The attached patch fixes the balloon driver for auto_translated mode.
