Michael Ellerman 17c743b9da selftests/sigaltstack: Fix ppc64 GCC build ... Building the sigaltstack test with GCC on 64-bit powerpc errors with: gcc -Wall sas.c -o /home/michael/linux/.build/kselftest/sigaltstack/sas In file included from sas.c:23: current_stack_pointer.h:22:2: error: #error "implement current_stack_pointer equivalent" 22 | #error "implement current_stack_pointer equivalent" | ^~~~~ sas.c: In function ‘my_usr1’: sas.c:50:13: error: ‘sp’ undeclared (first use in this function); did you mean ‘p’? 50 | if (sp < (unsigned long)sstack || | ^~ This happens because GCC doesn't define __ppc__ for 64-bit builds, only 32-bit builds. Instead use __powerpc__ to detect powerpc builds, which is defined by clang and GCC for 64-bit and 32-bit builds.
