From 6580376fe81093d3a796b7e8b8c3c0f9e620f89c Mon Sep 17 00:00:00 2001 From: Matteo Croce Date: Mon, 18 Mar 2019 02:32:36 +0100 Subject: percpu: stop printing kernel addresses commit 00206a69ee32f03e6f40837684dcbe475ea02266 upstream. Since commit ad67b74d2469d9b8 ("printk: hash addresses printed with %p"), at boot "____ptrval____" is printed instead of actual addresses: percpu: Embedded 38 pages/cpu @(____ptrval____) s124376 r0 d31272 u524288 Instead of changing the print to "%px", and leaking kernel addresses, just remove the print completely, cfr. e.g. commit 071929dbdd865f77 ("arm64: Stop printing the virtual memory layout").
