[ Upstream commit 00d872dd54 ]
The trace_adjust_address() will take a given address and examine the
persistent ring buffer to see if the address matches a module that is
listed there. If it does not, it will just adjust the value to the core
kernel delta. But if the address was for something that was not part of
the core kernel text or data it should not be adjusted.
Check the result of the adjustment and only return the adjustment if it
lands in the current kernel text or data. If not, return the original
address.
