    x86/efi: Enable runtime call flag checking · 9788375d
    Mark Rutland authored
    Define ARCH_EFI_IRQ_FLAGS_MASK for x86, which will enable the generic
    runtime wrapper code to detect when firmware erroneously modifies flags
    over a runtime services function call.
    
    For x86 (both 32-bit and 64-bit), we only need check the interrupt flag.
