Xen devel - Oct 2005 - [PATCH] Fix PAE shadow on a machine with RAM above 4G on x86_64 xen

Fix PAE shadow on a machine with RAM above 4G on x86_64 xen.
Currently, on a machine with RAM above 4G, we can not run 32bit VMX
guest on x86_64 xen, the root cause is that the PAE page table PDPT must
below 4G, this patch fixes this issue.
Also did some cleanup.
