When we get a PER i-fetch event on an EXECUTE or EXECUTE RELATIVE LONG instruction, because the executed instruction generated a PER i-fetch event, then the PER address points at the EXECUTE function, not the fetched one. Therefore, when filtering PER events, we have to take care of the really fetched instruction, which we can only get by reading in guest virtual memory. For icpt code 4 and 56, we directly have additional information about an EXECUTE instruction at hand. For icpt code 8, we always have to read in guest virtual memory.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
