Commit 79ca616 (v1.6.0) accidentally disabled legacy x86-only HMP commands pci_add, pci_del: it defined CONFIG_PCI_HOTPLUG only as make variable, not as preprocessor macro, killing the code conditional on defined(CONFIG_PCI_HOTPLUG_OLD). In all this time, nobody reported the loss. I only noticed it when I tried to test some error reporting change that forced me to touch this old crap again. Fun: git-log hw/pci/pci-hotplug-old.c shows our faith in the backward compatibility god has been strong enough to sacrifice at its altar about a dozen times, but not strong enough to even once verify the legacy feature's still there, let alone works. Remove the commands along with the code backing them. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Michael S.
