From 817bb6a4467366b6d1ecbb13a78450f91efd16bf Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Mon, 27 Feb 2017 15:29:11 +0100 Subject: [PATCH] ppc/xics: remove set_nr_servers() handler from XICSStateClass MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Today, the ICP (Interrupt Controller Presenter) objects are created by the 'nr_servers' property handler of the XICS object and a class handler. They are realized in the XICS object realize routine. Let's simplify the process by creating the ICP objects along with the XICS object at the machine level.
