Presumably another include needed:

arch/s390/lib/test_unwind.c:49:2: error: implicit declaration of function 'kmalloc' [-Werror=implicit-function-declaration]
arch/s390/lib/test_unwind.c:99:2: error: implicit declaration of function 'kfree' [-Werror=implicit-function-declaration]  

And more (these are coming from other's builds):

  drivers/remoteproc/qcom_q6v5_mss.c:772:3: error: implicit declaration of function 'kfree' [-Werror,-Wimplicit-function-declaration]
  drivers/remoteproc/qcom_q6v5_mss.c:808:2: error: implicit declaration of function 'kfree' [-Werror,-Wimplicit-function-declaration]
  drivers/remoteproc/qcom_q6v5_mss.c:1195:2: error: implicit declaration of function 'kfree' [-Werror,-Wimplicit-function-declaration]

They may have other causes as they are full linux-next builds (not just
after the merge of the vfs tree), but the timing is suspicious.

OK, here's a patch for both of these together:
