selftests/powerpc: Fix to use ucontext_t instead of struct ucontext

2018-02-13T11:44:18+00:00

With glibc 2.26 'struct ucontext' is removed to improve POSIX compliance, which breaks powerpc/alignment_handler selftest. Fix the test by using ucontext_t. Tested on ppc, works with older glibc versions as well. Fixes the following: alignment_handler.c: In function ‘sighandler’: alignment_handler.c:68:5: error: dereferencing pointer to incomplete type ‘struct ucontext’ ucp->uc_mcontext.gp_regs[PT_NIP] += 4; Signed-off-by: Harish Signed-off-by: Michael Ellerman

selftests: remove duplicated all and clean target

2017-01-05T20:41:35+00:00

Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to indicate the test program, extended test program and test files. It is easy to understand the purpose of these files. But mix of compiled and uncompiled files lead to duplicated "all" and "clean" targets. In order to remove the duplicated targets, introduce TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled objects. Also, the later patch will make use of TEST_GEN_XXX to redirect these files to output directory indicated by KBUILD_OUTPUT or O. And add this changes to "Contributing new tests(details)" of Documentation/kselftest.txt. Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan
