Support was added for kernel modules. This included adding the needed relocation types to the in-kernel relocator, and update the build logic to build modules for arm64. CTF data is not generated for modules due to a linker bug.

Shared page support was added. This allows gettimeofday(2) to be implemented in userland by directly accessing the timer register. This reduces the overhead of these calls as we no longer need to call into the kernel. This also moves the signal trampoline code away from the stack allowing for the stack to become non-executable.

CloudABI support for arm64 was added. This included moving the Machine Independent code into a separate file to be shared between all architectures. An issue in the arm64 kernel were found and fixed thanks to the CloudABI test suite.

Self-hosted poudriere package builds have been tested. These have complemented previous build using qemu usermode emulation. With this combination of self-hosted and qemu usermode building many broken packages have been fixed resulting in over 17000 ports building.

The machine dependent kernel support for single-stepping userland has been started. This allows debuggers, such as lldb, to step through an application while debugging.

Many small fixes have been made to FreeBSD. These include: fixing stack tracing through exceptions, print more information on data abort panics, cleanups of atomic functions, support for multi-pass driver attachment, fix userland stack alignment, cleanup early pagetable creation, fix asynchronous software trap handling, and enable interrupts in exception handlers were needed.
