+Subject: [PATCH 3/3] ssb: Do not disable PCI host on non-Mips
+
+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.
+
+Fixes: 58eae1416b80 ("ssb: Disable PCI host for PCI_DRIVERS_GENERIC")
