Mark Johnston 610141cebb Add stack_save_td_running(), a function to trace the kernel stack of a ... running thread. It is currently implemented only on amd64 and i386; on these architectures, it is implemented by raising an NMI on the CPU on which the target thread is currently running. Unlike stack_save_td(), it may fail, for example if the thread is running in user mode. This change also modifies the kern.proc.kstack sysctl to use this function, so that stacks of running threads are shown in the output of "procstat -kk". This is handy for debugging threads that are stuck in a busy loop.
