From 0f27cff8597d86f881ea8274b49b63b678c14a3c Mon Sep 17 00:00:00 2001 From: Prarit Bhargava Date: Thu, 30 Nov 2017 15:05:59 -0500 Subject: ACPI: sysfs: Make ACPI GPE mask kernel parameter cover all GPEs The acpi_mask_gpe= kernel parameter documentation states that the range of mask is 128 GPEs (0x00 to 0x7F). The acpi_masked_gpes mask is a u64 so only 64 GPEs (0x00 to 0x3F) can really be masked. Use a bitmap of size 0xFF instead of a u64 for the GPE mask so 256 GPEs can be masked.
