#     genirq: Fix export of irq_to_desc() for powerpc KVM
#     
#     Commit 64a1b95bb9fe ("genirq: Restrict export of irq_to_desc()")
#     removed the export of irq_to_desc() unless powerpc KVM is being built,
#     because there is still a use of irq_to_desc() in modular code there.
#     
#     However it used:
#     
#       #ifdef CONFIG_KVM_BOOK3S_64_HV
#     
#     Which doesn't work when that symbol is =m, leading to a build failure:
#     
#       ERROR: modpost: "irq_to_desc" [arch/powerpc/kvm/kvm-hv.ko] undefined!
#     
#     Fix it by checking for the definedness of the correct symbol which is
#     CONFIG_KVM_BOOK3S_64_HV_MODULE.
#
