2024-10-30powerpc64: Obviate the need for ROP protection in clone/clone3Sachin Monga1-16/+19
Save lr in a non-volatile register before scv in clone/clone3. For clone, the non-volatile register was unused and already saved/restored. Remove the dead code from clone. Signed-off-by: Sachin Monga <smonga@linux.ibm.com> Reviewed-by: Peter Bergner <bergner@linux.ibm.com>

2023-02-09powerpc64: Add the clone3 wrapperAdhemerval Zanella Netto1-0/+157
It follows the internal signature: extern int clone3 (struct clone_args *__cl_args, size_t __size, int (*__func) (void *__arg), void *__arg); The powerpc64 ABI requires an initial stackframe so the child can store/restore the TOC. It is create prior calling clone3 by adjusting the stack size (since kernel will compute the stack as stack plus size). Checked on powerpc64-linux-gnu (power8, kernel 6.0) and powerpc64le-linux-gnu (power9, kernel 4.18). Reviewed-by: Paul E. Murphy <murphyp@linux.ibm.com>
