From 012ea376a5948b025f260aa45d2a6ec5d96674ea Mon Sep 17 00:00:00 2001 From: Thomas Weissschuh Date: Wed, 7 Jan 2026 10:56:33 +0100 Subject: [PATCH] ARM: 9467/1: mm: Don't use %pK through printk MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Restricted pointers ("%pK") were never meant to be used through printk(). They can acquire sleeping locks in atomic contexts. Switch to %px over the more secure %p as this usage is a debugging aid, gated behind CONFIG_DEBUG_VIRTUAL and used by WARN().
