    ACPI: sysfs: Change ACPI_MASKABLE_GPE_MAX to 0x100 · a7583e72
    Yunfeng Ye authored
    The commit 0f27cff8 ("ACPI: sysfs: Make ACPI GPE mask kernel
    parameter cover all GPEs") says:
      "Use a bitmap of size 0xFF instead of a u64 for the GPE mask so 256
       GPEs can be masked"
    
    But the masking of GPE 0xFF it not supported and the check condition
    "gpe > ACPI_MASKABLE_GPE_MAX" is not valid because the type of gpe is
    u8.
    
    So modify the macro ACPI_MASKABLE_GPE_MAX to 0x100, and drop the "gpe >
    ACPI_MASKABLE_GPE_MAX" check. In addition, update the docs "Format" for
    acpi_mask_gpe parameter.
