From dde6f18a8779dcd88d9fd5d6336032fee7e07fcd Mon Sep 17 00:00:00 2001 From: Frederic Barrat Date: Fri, 3 Apr 2020 17:38:37 +0200 Subject: ocxl: Don't return trigger page when allocating an interrupt MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Existing users of ocxl_link_irq_alloc() have been converted to obtain the trigger page of an interrupt through xive directly, we therefore have no need to return the trigger page when allocating an interrupt. It also allows ocxl to use the xive native interface to allocate interrupts, instead of its custom service.
