arg0 should be an offset of the return point within the function, arg1 should be the return value. Previously the return probe had arguments as if for the entry probe. Tested on armv7. andrew noted that the same problem seems to be present on arm64, mips, and riscv. I am not sure if I will get around to fixing those. So, platform users or anyone looking to make a contribution please be aware of this opportunity. Reviewed by: markj MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D25685

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
