Bug#748052: [Xen-devel] dom0 USB failing with "ehci-pci: probe of 0000:00:1d.0 failed with error -110"

As this is a debug message anyway, it would be sensible for the extable
handler to print %pS of the left hand address. It would avoid needing
to refer back to xen-syms in cases like this.

Cleaning up descriptor patch
So in the page fault handler, we have some tests against kernel / user
CS which avoid the logic of actually figuring out the segment limit. I
propose we use the same trick as arch/i386/mm/extable.c, which simply
masks the RPL off and combines the segments together to test for faults
before setting the pnp_bios_is_utter_crap variable. In this case, we
can simply test:
if (likely((seg & 0xe8) == __KERNEL_CS)
and be done with any RPL masking at all. Perhaps this is best put in a
