The section 5.2.1.2 of the AAPCS says that the stack must be 8-byte aligned and this rule is broken when the thread restore_task_with_children() is forked by the function fork_with_pid() since the variable ca and its field stack are likely to be 4-byte aligned. This patch forces 8-byte alingment of the field cr_clone_arg::stack. This made the following tests pass on ARM: * static/shm, * static/ipc_namespace. Particulary the unaligned stack results in incorrect passing of the 64-bit argument to the function snprintf() in the function sysctl_write_u64().
