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. Changes in v3: - fix envp handling in startup assembly Changes in v2: - use __attribute__((unused)) instead of __maybe_unused - prefer aghi over lay, as lay is not present in all architecure levels - add -m64 CFLAG to force 64 bit mode for compiler that can do 31bit and 64bit mode 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 tools/include/nolibc/arch-s390.h | 222 ++++++++++++++++++ tools/include/nolibc/arch.h | 2 + tools/include/nolibc/sys.h | 2 + tools/include/nolibc/types.h | 53 +++-- tools/testing/selftests/nolibc/Makefile | 7 +- .../selftests/rcutorture/bin/functions.sh | 6 + .../selftests/rcutorture/bin/mkinitrd.sh | 2 +- 7 files changed, 269 insertions(+), 25 deletions(-) create mode 100644 tools/include/nolibc/arch-s390.h -- 2.34.1
