Hi all,

After merging the kbuild tree, today's linux-next build (arm
multi_v7_defconfig) produced these warnings:

WARNING: modpost: vmlinux.o(___ksymtab_gpl+mdio_bus_init+0x0): Section mismatch in reference from the variable __ksymtab_mdio_bus_init to the function .init.text:mdio_bus_init()
The symbol mdio_bus_init is exported and annotated __init
Fix this by removing the __init annotation of mdio_bus_init or drop the export.

Fix this by removing the __init annotation of xfrm4_protocol_init or drop the export.

The x86_64 allmodconfig build added these:
