From ebd8ea82441020f2781928b17f37ed9a0d2e4250 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Tue, 17 May 2016 16:43:02 +0200 Subject: [PATCH] pc: acpi: simplify build_legacy_cpu_hotplug_aml() signature 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.
