Mark Johnston 35c91b0c27 Implement per-CPU pmap activation tracking for RISC-V. ... This reduces the overhead of TLB invalidations by ensuring that we only interrupt CPUs which are using the given pmap. Tracking is performed in pmap_activate(), which gets called during context switches: from cpu_throw(), if a thread is exiting or an AP is starting, or cpu_switch() for a regular context switch. For now, pmap_sync_icache() still must interrupt all CPUs.
