[Xen-devel] Unable to start PAE Mini-OS from 0x0

["Puthiyaparambil, Aravindh" <aravindh.puthiyaparambil@xxxxxxxxxx>]

I am trying to start PAE Mini-OS from 0x0 so that I can get access to
all 4GB. But it is failing in the builder (line 838 xc_linux_build.c)
when it tries to pin the L3 table with the following error below.
Further more, I am not able to bring up Mini-OS from any other address
other than 0xc0000000.

Is there a restriction on this in i386 PAE? Could someone please explain
why?

Thanks,
