From: Steven Rostedt <[email protected]> On 32bit x86, _THIS_IP_ is not defined in asm/linkage.h. It happens to get included into lockdep.h via kernel.h pulling in trace_printk.h which includes instruction_pointer.h that has _THIS_IP_ defined when linkage.h does not.
In order to remove trace_printk.h from kernel.h, have lockdep.h include instruction_pointer.h directly.
