EXPORT_SYMBOL_GPL?
Interrupt-control macros (local_irq_enable/disable and friends) used
this symbol, so GPLing it made non-GPL modules fail. We made a bunch
of the macros proper functions so this may no longer be the case.
Given that this is just a page exported from the hypervisor, it doesn't
make much sense to impose a GPL requirement on this symbol (to put it
another way, this is more part of the Xen ABI than the Linux API, so
Linux can't make much claim to it).
