We need to tell vm_fault the reason for the fault was because we tried to execute from the memory location. Without this it may return with success as we only request read-only memory, then we return to the same location and try to execute from the same memory address. This leads to an infinite loop raising the same fault and returning to the same invalid location. MFC after: 1 week Sponsored by: DARPA, AFRL Differential Revision: https://reviews.freebsd.org/D18511

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.
