tracing: Choose static tp_printk buffer by explicit nesting count Currently, the trace_printk code chooses which static buffer to use based on what type of atomic context (NMI, IRQ, etc) it's in. Simplify the code and make it more robust: simply count the nesting depth and choose a buffer based on the current nesting depth. The new code will only drop an event if we nest more than 4 deep, and the old code was guaranteed to malfunction if that happened.
