* in user thread case the registers had been copied as part of task_struct already; no need to do it in copy_thread(). * no need to store kernel stack pointer into regs->r21; we know its offset anyway. * no need to clobber r3 in sys_fork_wrapper and friends - r28 will do just as well and *it* will be overwritten anyway. * no need to mess with storing the return address for child - it should just use syscall_exit. * no need to bother with separate stack frame for sys_clone() - just branch there and be done with that. * no need to bother with wrapper_exit - we need it only on the child_return, so let's just do it there. * use the same ksp for kernel threads and userland ones, while we are at it, and let ret_from_kernel_execve() go through the normal syscall_exit. More straightforward is better here... [fixes from jejb folded] Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> |
