Yes, it is.  HIGHPTE isn't recommended in general because it imposes a
fairly high performance hit (even without Xen, but worse with).  And,
worse, at the moment I don't have any plausible fix for the bug.  Its
really a left-over from the days of 32-bit machines with much more than
4G of memory; these days you'd use 64-bit.
