From 3fa9f9df1e9199e43dbbdd69e0cb814e655e3d8b Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Mon, 1 Aug 2016 08:11:18 +0200 Subject: [PATCH 18/99] pc: acpi: simplify build_legacy_cpu_hotplug_aml() signature RH-Author: Igor Mammedov Message-id: <1470039143-24450-14-git-send-email-imammedo@redhat.com> Patchwork-id: 71629 O-Subject: [RHEV-7.3 qemu-kvm-rhev PATCH 13/78] pc: acpi: simplify build_legacy_cpu_hotplug_aml() signature Bugzilla: 1087672 RH-Acked-by: Marcel Apfelbaum RH-Acked-by: David Gibson RH-Acked-by: Eduardo Habkost since IO block used by CPU hotplug is fixed size and initialized it the same file as build_legacy_cpu_hotplug_aml() just use ACPI_GPE_PROC_LEN directly instead of passing it around in several files.
