[Xen-ia64-devel] [patch] don't allocate bitmap from low pool

[Jes Sorensen <jes@xxxxxxx>]

Hi,

There is no reason to allocate this bitmap from the low pages pool
since all pages are identity mapped on ia64.

With this and the previous patch I posted, I can boot the dom0 kernel
directly on sn hardware.

Cheers,
Jes

No need to allocate contiguous_bitmap out of the low pages pool as all
pages are directly accessible on an ia64.
