4.15-stable review patch. If anyone has any objections, please let me know.
------------------ From: Kees Cook <[email protected]> commit 0862ca422b79cb5aa70823ee0f07f6b468f86070 upstream. The BUG and stack protector reports were still using a raw %p. This changes it to %pB for more meaningful output.
