Thanks for reporting.

Daniel,

Could you please squash the following fix to the commit above?

diff --git a/kernel/reboot.c b/kernel/reboot.c
index 07eb6537ed8b..f814568525f1 100644

  }

  static int __init reboot_setup(char *str)
  {

x86_64 allmodconfig builds successfully with this change.

Thanks,
