ACPI: sysfs: Make ACPI GPE mask kernel parameter cover all GPEs
[ Upstream commit 0f27cff8597d86f881ea8274b49b63b678c14a3c ] 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. Fixes: 9c4aa1eecb48 (ACPI / sysfs: Provide quirk mechanism to prevent GPE flooding) Signed-off-by: Prarit Bharava <prarit@redhat.com> Signed-off-by: Rafael J.
