+ <p>Support was added for kernel modules. This included adding
+ the needed relocation types to the in-kernel relocator, and
+ updating the build logic to build modules for arm64. CTF data is
+ currently not generated for modules due to a linker bug.</p>
+
+ <p>Shared page support was added. This allows
+ <tt>gettimeofday(2)</tt> 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.</p>
+
+ <p>CloudABI support for arm64 was added. This included moving
+ the machine-independent code into a separate file to be shared
+ among all architectures. An issue in the arm64 kernel was found
+ and fixed thanks to the CloudABI test suite.</p>
+
+ <p>Self-hosted poudriere package builds have been tested.
+ These complement the previous build strategy of using qemu
+ usermode emulation. With this combination of self-hosted and qemu
+ usermode building, many ports that used to be broken on arm64 have
+ been fixed resulting in over 17000 ports building for the
+ architecture.</p>
+
+ <p>The machine-dependent portions of kernel support for
+ single-stepping userland binaries has been started. This will
+ allow debuggers, such as <tt>lldb</tt>, to step through an
+ application while debugging.</p>
+
+ <p>Many small fixes have been made to &os;/arm64. These
+ include fixing stack tracing through exceptions, printing more
+ information about "data abort" kernel panics, cleaning
+ up the atomic functions, supporting multi-pass driver attachment,
+ fixing userland stack alignment, cleaning up early page table
+ creation, fixing asynchronous software trap handling, and enabling
+ interrupts in exception handlers.</p>
