Subject: [PATCH v4 03/19] ARM: mach-ux500: use SGI0 to wake up the other core
Date: Thu, 3 Jan 2013 11:54:12 -0600 [thread overview]
Message-ID: <1357235668-9450-4-git-send-email-robherring2@gmail.com> (raw)
In-Reply-To: <1357235668-9450-1-git-send-email-robherring2@gmail.com>
From: Srinidhi Kasagar <srinidhi.kasagar@stericsson.com>
The commit 7d28e3eaa1a8e951251b942e7220f97114bd73b9
("ARM: ux500: wake secondary cpu via resched") makes use
of schedule IPI to wake up the secondary core which seems
incorrect. Rather use SGI0.
