Hi,

these patches add support for the s390 architecture both to nolibc
and rcutorture. Note that this only adds support for the 64 bit
version, no support for 31 bit (compat) is added. For nolibc it
includes one bugfix to make the fd_set datatype match the kernel
type.

Sven Schnelle (5):
  nolibc: fix fd_set type
  nolibc: add support for s390
  selftests/nolibc: add s390 support
  rcutorture: add support for s390
  rcutorture: build initrd for rcutorture with nolibc
