4.15-stable review patch.  If anyone has any objections, please let me know.

commit a9e6d44ddeccd3522670e641f1ed9b068e746ff7 upstream.

After upgrading an old laptop to 4.15-rc9, I found that the eth0 and
wlan0 interfaces had disappeared.  It turns out that the b43 and b44
drivers require SSB_PCIHOST_POSSIBLE which depends on
PCI_DRIVERS_LEGACY, a config option that only exists on Mips.
