[PATCH 3/3] selftests/bpf: Define SYS_PREFIX for powerpc

SYS_PREFIX was missing for a powerpc, which made a kprobe test to sys_prctl fail. Add missing SYS_PREFIX for powerpc. Fixes: 7e92e01b7245 ("powerpc: Provide syscall wrapper") Fixes: 94746890202c ("powerpc: Don't add __powerpc_ prefix to syscall entry points") Signed-off-by: Saket Kumar Bhaskar

[PATCH 1/3] libbpf: Fix accessing the syscall argument on powerpc

Since commit 7e92e01b7245 ("powerpc: Provide syscall wrapper"), powerpc selects ARCH_HAS_SYSCALL_WRAPPER so let's use the generic implementation of PT_REGS_SYSCALL_REGS(). Also, allow overriding PT_REGS_PARM1{_CORE}_SYSCALL for powerpc as powerpc needs orig_gpr3, similar to s390 and arm64. Signed

[PATCH 2/3] libbpf: Remove powerpc prefix from syscall function names

Since commit 94746890202cf ("powerpc: Don't add __powerpc_ prefix to syscall entry points") drops _powerpc prefix to syscall entry points, even though powerpc now supports syscall wrapper, so /proc/kallsyms have symbols for syscall entry without powerpc prefix(sys_*). For this reason, arch specifi

[PATCH 0/3] Fix test_bpf_syscall_macro selftest on powerpc

Since, syscall wrapper is supported on powerpc with syscall entry symbols as sys_*, changes done to fix selftests like test_bpf_syscall_macro, attach_probe/auto, etc. Saket Kumar Bhaskar (3): libbpf: Fix accessing the syscall argument on powerpc libbpf: Remove powerpc prefix from syscall func
