Subject: [patch 03/14] x86/apic: Implement default single target IPI function
Date: Wed, 04 Nov 2015 22:57:01 -0000 [thread overview]
Message-ID: <20151104220848.898543767@linutronix.de> (raw)
In-Reply-To: 20151104215716.810356093@linutronix.de
[-- Attachment #1: x86-apic--Implement-default-single-target-IPI-function --]
[-- Type: text/plain, Size: 1364 bytes --]
apic_physflat and bigsmp_apic can share that implementation.
