Note that unlike the referenced 82b355d161c9 patch, this is no longer needed for correctness, since modern kernels generate the asm/unistd.h from the syscall.tbl based on arch/loongarch/kernel/Makefile.syscalls, which leaves out the references to newstat. The patch is still useful of course, but only to slightly reduce the size of the kernel image by eliminating dead code. Arnd
