4.13-stable review patch. If anyone has any objections, please let me know.
------------------ From: Julien Thierry <[email protected]> commit f9b269f3098121b5d54aaf822e0898c8ed1d3fec upstream. When HYP code runs into branch profiling code, it attempts to jump to unmapped memory, causing a HYP Panic. Disable the branch profiling for code designed to run at HYP mode.
