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)
