Log message:
Support more than 64 bits for amd64 TLB shootdown IPI masks
The TLB shootdown code used a uint64_t to track which CPUs needed to have
their TLB remotely flushed during pmap operations. This allowed for up to
64 CPUs maximum on amd64.
This diff changes the single uint64_t mask to an array of uint8_t masks,
sized based on MAXCPUS, and utilizes the bitmask macros in param.h to
manipulate these masks.
