Subject: [PATCH] Profiler: Subtract the kernel's base address when searching
 for symbols

Now that the kernel is compiled as a PIE, all addresses are relative to
the loaded base address, so Symbolication::kernel_base has to be
subtracted off from the absolute addresses if we want to symbolicate
them.
