Currently we have sys_sigpending and sys_old_getrlimit defined to use COMPAT_SYS() in systbl.h, but then both are #defined to sys_ni_syscall in systbl.S. This seems to have been done when ppc and ppc64 were merged, in commit 9994a338 "Introduce entry_{32,64}.S, misc_{32,64}.S, systbl.S". AFAICS there's no longer (or never was) any need for this, we can just use SYSX() for both and remove the #defines to sys_ni_syscall. The expansion before was: #define COMPAT_SYS(func) .llong .sys_##func,.compat_sys_##func #define sys_old_getrlimit sys_ni_syscall COMPAT_SYS(old_getrlimit) => .llong .sys_old_getrlimit,.compat_sys_old_getrlimit => .llong .sys_ni_syscall,.compat_sys_old_getrlimit After is: #define SYSX(f, f3264, f32) .llong .f,.f3264 SYSX(sys_ni_syscall, compat_sys_old_getrlimit, sys_old_getrlimit) => .llong .sys_ni_syscall,.compat_sys_old_getrlimit ie. they are equivalent. Finally both COMPAT_SYS() and SYSX() evaluate to sys_ni_syscall in the Cell SPU code.
