Separate kernel/non-kernel addresses in quipper space Kernel objects are mapped to a quipper space separate from that of the non-kernel objects. However this presents a problem when reconstructing the perf events from mapped addresses. Samples in the kernel cannot always be identified by a pid as they might have the pid of a non-kernel process that is calling into the kernel. This patch arranges the addresses so that kernel addresses are distinguishable from non-kernel addresses even when mapped to quipper space.
