skrll | risc-v: MULTIPROCESSOR support
Add MULTIPROCESSOR support for RISC-V, but leave disabled for the moment
as it's not 100% stable.
Some other improvements to spl and cpu identification / reporting.

skrll | Fix CLKF_INTR so that not all time is shown as being spent in interrupts.

skrll | RISC-V support that works on QEMU with a single hart.
Thanks for Simon Burge for plic(4).

simonb | Use better types and struct member names in the clockframe.
Avoid a magic number in CLKF_USERMODE().

ryo | 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.

ad | Fix false sharing problems with cpu_info. Identified with tprof(8).
This was a very nice win in my tests on a 48 CPU box.
- Reorganise cpu_data slightly according to usage.
- Put cpu_onproc into struct cpu_info alongside ci_curlwp (now is ci_onproc).
- On x86, put some items in their own cache lines according to usage, like
the IPI bitmask and ci_want_resched.

ad | mi_userret(): take care of calling preempt(), set spc_curpriority directly,
and remove MD code that does the same.

_KMEMUSER only needs struct cpu_info

matt | Define curcpu() as lwp_getcpu(curlwp) since curlwp is always in the "tp"
(thread pointer) register.

matt | Beginnings of RISCV kernel support. Note that the pmap support is not yet
committed and probably won't be for awhile. This is mostly preliminary
waiting for the supervisor specification to come out. Lots of missing pieces
but it mostly builds.
