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.

WARNING: modpost: vmlinux.o(___ksymtab+xfrm4_protocol_init+0x0): Section mismatch in reference from the variable __ksymtab_xfrm4_protocol_init to the function .init.text:xfrm4_protocol_init()
The symbol xfrm4_protocol_init is exported and annotated __init 
Fix this by removing the __init annotation of xfrm4_protocol_init or drop the export.

The x86_64 allmodconfig build added these:

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

WARNING: modpost: vmlinux.o(___ksymtab_gpl+ixp4xx_timer_setup+0x0): Section mismatch in reference from the variable __ksymtab_ixp4xx_timer_setup to the function .init.text:ixp4xx_timer_setup()
The symbol ixp4xx_timer_setup is exported and annotated __init 
Fix this by removing the __init annotation of ixp4xx_timer_setup or drop the export.

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

WARNING: modpost: net/ipv6/ipv6.o(___ksymtab+seg6_hmac_init+0x0): Section mismatch in reference from the variable __ksymtab_seg6_hmac_init to the function .init.text:seg6_hmac_init()
