PAGE_SIZE should be PAGE_SHIFT. If you fix that then you may discover that
dom0 can no longer be built (since there is not enough memory below 64GB to
build a ~256GB dom0, which is the default that the dom0 builder will go for)
so make sure you have a suitably restrictive dom0_mem= option on your Xen
command line. As Ian says we should fix that more nicely.
