Need export all related functions and symbols for various modules with
allmodconfig. The related errors:
MODPOST 2879 modules
ERROR: "__vmyield" [sound/sound_firmware.ko] undefined!
ERROR: "__phys_offset" [sound/drivers/snd-dummy.ko] undefined!
ERROR: "ioremap_nocache" [drivers/char/ipmi/ipmi_si.ko] undefined!
ERROR: "__iounmap" [drivers/char/ipmi/ipmi_si.ko] undefined!
...
For including files, need "linux/*" first, then "asm/*". All related
included files and symbols need be sorted by alphabetical order.
