[Qemu-devel] [PATCH for-QEMU-4.1 v5 01/29] hw/pci/pci-stub: Add msi_enabled() and msi_notify() to the pci stubs

[Thomas Huth <thuth@redhat.com>]

Some machines have an AHCI adapter, but no PCI. To be able to
compile hw/ide/ahci.c without CONFIG_PCI, we still need the two
functions msi_enabled() and msi_notify() for linking.
This is required for the new Kconfig-like build system, if a user
wants to compile a QEMU binary with just one machine that has AHCI,
but no PCI, like the ARM "cubieboard" for example.
