I see that the three syscalls seccomp, getrandom and memfd_create are not wired because of which we get a warning while compilation. So I wired them up in this patch. What else needs to be done? I tried the memfd_test after compiling this kernel, but it is failing. What am I missing for this to work? Any advice is really appreciated! :) Signed-off-by: Pranith Kumar <redacted> --- arch/powerpc/include/asm/systbl.h | 3 +++ arch/powerpc/include/asm/unistd.h | 2 +- arch/powerpc/include/uapi/asm/unistd.h | 3 +++ 3 files changed, 7 insertions(+), 1 deletion(-)
