Subject: [PATCH 13/17] extable: Adjust system_state checks
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.11/older/patches-4.11.8-rt5.tar.xz
|
|
|
|
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 core_kernel_text() to handle the extra
|
|
states, i.e. to cover init text up to the point where the system switches
|
|
to state RUNNING.
