[PATCH RFC 10/22] drivers: base: Move cpu_dev_init() after node_dev_init()

From: Russell King (Oracle) <hidden>
Date: 2023-11-07 10:30:39
Also in: kvmarm, linux-acpi, linux-arch, linux-doc, linux-pm, linux-riscv, lkml, loongarch
Subsystem: driver core, kobjects, debugfs and sysfs, the rest · Maintainers: Greg Kroah-Hartman, "Rafael J. Wysocki", Danilo Krummrich, Linus Torvalds

From: James Morse <james.morse@arm.com>

NUMA systems require the node descriptions to be ready before CPUs are
registered. This is so that the node symlinks can be created in sysfs.

Currently no NUMA platform uses GENERIC_CPU_DEVICES, meaning that CPUs
are registered by arch code, instead of cpu_dev_init().

Move cpu_dev_init() after node_dev_init() so that NUMA architectures
can use GENERIC_CPU_DEVICES.
