[PATCH] arm64: Demote boot and shutdown messages to pr_debug
From: Florian Fainelli <f.fainelli@gmail.com>
Date: 2019-04-30 22:39:14
Also in:
lkml
Subsystem:
arm64 port (aarch64 architecture), the rest · Maintainers:
Catalin Marinas, Will Deacon, Linus Torvalds
Similar to commits c68b0274fb3cf ("ARM: reduce "Booted secondary
processor" message to debug level") and 035e787543de7 ("ARM: 8644/1: Reduce "CPU:
shutdown" message to debug level"), demote the secondary_start_kernel()
and __cpu_die() messages from info, respectively notice to debug. While
we are at it, also do this for cpu_psci_cpu_kill() which is redundant
with __cpu_die().
This helps improve the amount of possible hotplug cycles by around +50%
on ARCH_BRCMSTB.
