Applied, thanks!

I also added the patch below:

Subject: [PATCH 2/2] kbuild: enable arch/s390/include/uapi/asm/zcrypt.h for
 uapi header test

Masahiro Yamada changed the zcrypt.h header file to use __u{16,32,64}
instead of uint{16,32,64}_t with ("s390: use __u{16,32,64} instead of
uint{16,32,64}_t in uapi header").

This makes all s390 header files pass - remove zcrypt.h from the blacklist.
