[PATCH v2 01/12] arch: Export cpu_logical_map to modules
From: Florian Fainelli <f.fainelli@gmail.com>
Date: 2021-09-28 02:27:55
Also in:
linux-devicetree, linux-mips, linux-sh, lkml
Subsystem:
arm port, arm64 port (aarch64 architecture), superh, the rest · Maintainers:
Russell King, Catalin Marinas, Will Deacon, Yoshinori Sato, Rich Felker, John Paul Adrian Glaubitz, Linus Torvalds
In order to allow drivers/irqchip/irq-bcm7038-l1.c to be built as a
module and usable in GKI, export cpu_logical_map or __cpu_logical_map
towards the modules. This follows what MIPS has been doing since
2dc2ae344e0e ("MIPS: Export __cpu_number_map and __cpu_logical_map.")
