Kernel debuggers depend on symbol names to find stack frames with a trapframe rather than a normal stack frame. The labels used for the shared interrupt entry point for the PTI and non-PTI cases did not match the existing patterns confusing debuggers. Add the '.L' prefix to mark these symbols as local so they are not visible in the symbol table.
