Jessica Clarke 4e3a43905e ofw_pci: Fix incorrectly sized softc causing pci(4) out-of-bounds reads
We do not include sys/rman.h and so machine/resource.h ends up not being
included by the time pci_private.h is included. This means PCI_RES_BUS
is never defined, and so the sc_bus member of pci_softc is not present
when compiling ofw_pci, resulting in the wrong softc size being passed
to DEFINE_CLASS_1 and thus any attempts by pci(4) to access that member
are out-of-bounds reads or writes.

This is pretty fragile; arguably pci_private.h should be including
sys/rman.h, but this is the minimal needed change to fix the bug whilst
maintaining the status quo.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
