[Xen-devel] [patch] pae: build fix

[Gerd Knorr <kraxel@xxxxxxx>]

  Hi,

The patch below is needed to make pae-enabled xen build.  Not
sure why the intpte_t cast was added and whenever it is a good
idea to remove it.  Problem is that PAGE_MASK is used to
page-align both physical and virtual addresses, and the cast
causes build failures for the virtual address case.

Comments?

  Gerd
