portfeatures(9): the man page for the __HAVE macros
The man page itself is a skeleton/template for now. Please add short
descriptions and xrefs. If the target man page doesn't yet document
relevant __HAVE macros (hi, mutex(9)), please add something there,
possibly in a .Sh IMPLEMENTATION NOTES section.
fix typos
Document __HAVE_UCAS_FULL and __HAVE_UCAS_MP.

+.
+.Sh DESCRIPTION
+Machine-independent kernel code adapts to differences in hardware
+capabilities provided by the machine-dependent parts of the kernel.
+A port declares its capabilities by defining various
+.Li __HAVE_ Ns Ar feature
+macros.
+This manual page provides an index of such macros with pointers to
+other manual pages in the kernel section that provide all the relevant
+details.

+.
+.\" ---------
+.It Dv __HAVE_MUTEX_STUBS Pq Xr mutex 9
+The port provides fast path mutex enter and exit stubs.
+.
+.\" ---------
+.It Dv __HAVE_PREEMPTION Pq Xr cpu_need_resched 9
+The port can preempt kernel lwps with
+.Dv RESCHED_KPREEMPT .
+.
+.\" ---------
+.It Dv __HAVE_PTRACE_MACHDEP
+The port has MD
+.Xr ptrace 2
+requests, defines
+.Dv PTRACE_MACHDEP_REQUEST_CASES
+macro with
+.Ic case
+labels for its MD requests.
+.
+.\" ---------
+.It Dv __HAVE_RAS Pq Xr ras 9
+The port supports restartable atomic sequences.
+.
+.\" ---------
+.It Dv __HAVE_SIMPLE_MUTEXES Pq Xr mutex 9
+The port provides a CAS function that is either MP-safe, or does not
+need to be MP safe.
+Adaptive mutexes on these architectures do not require an additional
+interlock.
+.
+.\" ---------
+.It Dv __HAVE_SPIN_MUTEX_STUBS Pq Xr mutex 9
+The port provides fast path enter and exit stubs for spin mutexes.
+.
+.\" ---------
+.It Dv __HAVE_UCAS_FULL Pq Xr ucas 9
+The port provides a full implementation of the low-level primitives
+required for atomic compare-and-swap operations to user-space addresses.
+.
+.\" ---------
+.It Dv __HAVE_UCAS_MP Pq Xr ucas 9
+The port does not provide a full implementation of the low-level
+primitives required for atomic compare-and-swap operations to user-space
+addresses, but does provide an implementation of those primitives that
+can be used if
+.Pq and only if
+the system has more than one processor.
