Revision 11cc92eb747aace5aa2b54b65b5cb8325a8981de authored by Michael Ellerman on 25 December 2020, 11:30:58 UTC, committed by Linus Torvalds on 25 December 2020, 19:02:39 UTC
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.
Fixes: 64a1b95bb9fe ("genirq: Restrict export of irq_to_desc()")
