From e377cd8221ebbe0b517861aa3d823bb42f9abbd4 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Sun, 15 Jan 2017 03:59:00 +0100 Subject: ARM: 8640/1: Add support for CONFIG_DEBUG_VIRTUAL x86 has an option: CONFIG_DEBUG_VIRTUAL to do additional checks on virt_to_phys calls. The goal is to catch users who are calling virt_to_phys on non-linear addresses immediately. This includes caller using __virt_to_phys() on image addresses instead of __pa_symbol(). This is a generally useful debug feature to spot bad code (particulary in drivers).
