Subject: [PATCH v2] arch: hexagon: kernel: hexagon_ksyms.c: export related
 symbols which various modules need

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!
  ...
