Joel Sing	ab242dcbc9	syscall: implement rawVforkSyscall for linux/ppc64x and linux/s390x ... This allows the use of CLONE_VFORK and CLONE_VM for fork/exec, preventing "fork/exec ...: cannot allocate memory" failures from occuring when attempting to execute commands from a Go process that has a large memory footprint. Additionally, this should reduce the latency of fork/exec on these platforms. The same problem was addressed on linux/amd64 via issue #5838.

Tobias Klauser	36951a9f63	syscall: support syscalls without error return on Linux ... Add the rawSyscallNoError wrapper function which is used for Linux syscalls that don't return an error and convert all applicable occurences of RawSyscall to use it instead.
