From ff48cd26fc4889b9deb5f9333d3c61746e450b7f Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 16 May 2017 20:42:45 +0200 Subject: [PATCH] printk: Adjust system_state checks To enable smp_processor_id() and might_sleep() debug checks earlier, it's required to add system states between SYSTEM_BOOTING and SYSTEM_RUNNING. Adjust the system_state check in boot_delay_msec() to handle the extra states.
