Improved the performance of kernel profiling on MULTIPROCESSOR, and possible to get profiling data for each CPU.
...
In the current implementation, locks are acquired at the entrance of the mcount
internal function, so the higher the number of cores, the more lock conflict
occurs, making profiling performance in a MULTIPROCESSOR environment unusable
and slow. Profiling buffers has been changed to be reserved for each CPU,
improving profiling performance in MP by several to several dozen times.
- Eliminated cpu_simple_lock in mcount internal function, using per-CPU buffers.
- Add ci_gmon member to struct cpu_info of each MP arch.
- Add kern.profiling.percpu node in sysctl tree.
- Add new -c <cpuid> option to kgmon(8) to specify the cpuid, like openbsd.
For compatibility, if the -c option is not specified, the entire system can be
operated as before, and the -p option will get the total profiling data for
all CPUs.

for 64 bit mips platforms where we built userland largely as n32 by
...
default, build a handful of tools as n64 so they work properly.
unfortunately, they're also static as dynamic n64 has a problem.
of these tools pstat is probably the lowest hanging fruit to convert
to sysctl. systat would be close were it not for the netstat screen,
which includes netstat itself.
the rest are difficult to perhaps foolish.
the upside is that netstat, pmap and fstat all work properly now.

using `.Nm ""' if there's stuff following, or for the 2nd and so on
occurrences in a SYNOPSIS
