From 6e03f66c001790d6ca853c68a56c87460bc86467 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 10 Jan 2017 18:43:54 +0200 Subject: [PATCH] locking/jump_labels: Update bug_at() boot message First of all, %*ph specifier allows to dump data in hex format using the pointer to a buffer. This is suitable to use here. Besides that Thomas suggested to move it to critical level and replace __FILE__ by explicit mention of "jumplabel".
