Mark Johnston c31c881f7e Fix the test used to wait for AP startup on x86, arm64, riscv ... On arm64, testing pc_curpcb != NULL is not correct since pc_curpcb is set in pmap_switch() while the bootstrap stack is still in use. As a result, smp_after_idle_runnable() can free the boot stack prematurely. Take a different approach: use smp_rendezvous() to wait for all APs to acknowledge an interrupt. Since APs must not enable interrupts until they've entered the scheduler, i.e., switched off the boot stack, this provides the right guarantee without depending as much on the implementation of cpu_throw(). And, this approach applies to all platforms, so convert x86 and riscv as well.
