Xen and 3.2.55

[gaima]

Hi,

Commit 3d39f46966283b73145304c1fa69b2ee12d39077 is making it pretty tricky to enable Xen dom0 support.
There seems to be a circular issue with PARAVIRT_GUEST (or maybe PARAVIRT) being necessary to be a dom0.
I got quite lost in the dependencies. I did find two ways out to enable Xen though.

1) Add "|| GRKERNSEC_CONFIG_VIRT_XEN" to the "depends on" for menuconfig PARAVIRT_GUEST.
2) Enable CONFIG_X86_EXTENDED_PLATFORM and CONFIG_X86_VSMP.

Option 2 isn't very practical as I don't have EM64T hardware.
