Thanks for looking at it.  I saw this yesterday too and am looking at
fixing it.  I dont usually do an allmodconfig test, and haven't seen
most of these before.

I have looked into these and fixed, will send patches soon.

>From below we have

  __ioremap - already fixed during last merge window
  iounmap - already fixed during last merge window

  empty_zero_page - asm symbol, need to export
    pm_power_off - need to export
  __ucmpdi2 - gcc builtin, to export
  __clear_user - asm symbol, need to export
  __get_user_bad - this is a get_user bug
