kbuild test robot report below error for randconfig:

  arch/x86/kernel/ksysfs.c: In function 'get_setup_data_paddr':
  arch/x86/kernel/ksysfs.c:81:3: error: implicit declaration of function 'ioremap_cache' [-Werror=implicit-function-declaration]
  arch/x86/kernel/ksysfs.c:86:3: error: implicit declaration of function 'iounmap' [-Werror=implicit-function-declaration]

Fix it by including &lt;asm/io.h&gt; in ksysfs.c
