Hi Will,

Commit 8d35d32d0148 ("kvm tools: add generic device registration
mechanism") introduced a tree-based device lookup-by-bus mechanism as
well as iterators to enumerate the devices on a particular bus.
Whilst both x86 and ppc were converted by the original patch, the
spapr
pci changes were incomplete, so include the required changes here.
Compile-tested only on ppc64 970mp. Note that I had to hack the
Makefile
in order to build guest_init.o with a toolchain defaulting to ppc:
$(GUEST_INIT): guest/init.c
$(E) " LINK " $@
- $(Q) $(CC) -static guest/init.c -o $@
- $(Q) $(LD) -r -b binary -o guest/guest_init.o $(GUEST_INIT)
+ $(Q) $(CC) -m64 -static guest/init.c -o $@
+ $(Q) $(LD) -m elf64ppc -r -b binary -o guest/guest_init.o
$(GUEST_INIT)
$(DEPS):

I lack PPC
But this patch appears too good
To be left aside
