Some IMA functions can check arch-specific status before running. For example, the ima_load_data function or the boot param "ima_appraise=3D" should not be executed when UEFI secure boot is enabled. We want to fill the gap in order to complete the IMA support on ARM64. Changes in v2: - Separate get_sb_mode() from x86 so all EFI-based architectures can reuse the same function. - Refactor arch/arm64/kernel/ima_arch.c based on Ard's patch[1].
