Thanks. I applied the patches, but moved the arm64 selftest patch to be the last one. FYI nolibc now has a proper prctl() implementation you might want to use. Also your vfork() selftest uncovered a bug in the brandnew SuperH support. > Signed-off-by: Mark Brown <broo...@kernel.org> > --- > Changes in v3: > - Stylistic nits in the GCS vfork() test. > - SPARC has a non-standard vfork() ABI which needs handling. > - Link to v2: > https://lore.kernel.org/r/20250610-arm64-gcs-vfork-exit-v2-0-929443dfc...@kernel.org > > Changes in v2: > - Add replacement of ifdef with if defined() in nolibc since the code > doesn't reflect the coding style. > - Remove check for arch specific vfork(). > - Link to v1: > https://lore.kernel.org/r/20250609-arm64-gcs-vfork-exit-v1-0-baad0f085...@kernel.org > > --- > Mark Brown (4): > tools/nolibc: Replace ifdef with if defined() in sys.h > tools/nolibc: Provide vfork() > kselftest/arm64: Add a test for vfork() with GCS > selftests/nolibc: Add coverage of vfork() > > tools/include/nolibc/arch-sparc.h | 16 +++++++ > tools/include/nolibc/sys.h | 59 ++++++++++++++++++------- > tools/testing/selftests/arm64/gcs/basic-gcs.c | 63 > +++++++++++++++++++++++++++ > tools/testing/selftests/nolibc/nolibc-test.c | 23 ++++++++-- > 4 files changed, 142 insertions(+), 19 deletions(-) > --- > base-commit: 86731a2a651e58953fc949573895f2fa6d456841 > change-id: 20250528-arm64-gcs-vfork-exit-4a7daf7652ee > > Best regards, > -- > Mark Brown <broo...@kernel.org> >
