| |
From: Leon Romanovsky <leonro@mellanox.com>
Kernel is booted with less possible CPUs (possible_cpus kernel boot option) than available CPUs will have prints like this:
[ 1.131039] APIC: NR_CPUS/possible_cpus limit of 8 reached. Processor 55/0x1f ignored. [ 1.132228] ACPI: Unable to map lapic to logical cpu number
Those warnings are printed for every not-enabled CPU and on the systems with large number of such CPUs, we see a lot of those prints for default print level.
Simple conversion of those prints to be in debug level removes them while leaving the option to debug system.
