[Qemu-devel] [PATCH 08/15] hw/pci/pci.h: Don't include qemu-common.h

[Markus Armbruster]

qemu-common.h should only be included by .c files.  Its file comment
explains why: "No header file should depend on qemu-common.h, as this
would easily lead to circular header dependencies."

hw/pci/pci.h includes qemu-common.h, but its users only need pcibus_t
and PCIHostDeviceAddress from it.  Move them to hw/pci/pci.h and drop
the ill-advised include.  Include hw/pci/pci.h where the moved stuff
is now missing.  Except we can't in target-i386/kvm_i386.h, because
that would break the i386-linux-user compile.  Add
PCIHostDeviceAddress to qemu/typedefs.h instead.
