Subject: [PATCH v2 2/2] ARM: smp: Moved cpu_logical_map[] to smp.h
Date: Mon, 3 Jun 2019 16:18:30 -0700 [thread overview]
Message-ID: <20190603231830.24129-3-f.fainelli@gmail.com> (raw)
In-Reply-To: <20190603231830.24129-1-f.fainelli@gmail.com>
asm/smp.h is included by linux/smp.h and some drivers, in particular
irqchip drivers can access cpu_logical_map[] in order to perform SMP
affinity tasks. Make arm64 consistent with other architectures here.
