Re: [PATCH] powerpc: Wire up clone3 syscall

[Arseny Solokha]

Hi,

may I also ask to provide ppc_clone3 symbol also for 32-bit powerpc? Otherwise
Michael's patch breaks build for me:

  powerpc-e500v2-linux-gnuspe-ld: arch/powerpc/kernel/systbl.o: in function 
`sys_call_table':
  (.rodata+0x6cc): undefined reference to `ppc_clone3'
  make: *** [Makefile:1060: vmlinux] Error 1

The patch was tested using Christian's program on a real e500 machine.

I don't think this trivial hunk deserves a separate patch submission.

Thanks,
