    clocksource: Disallow drivers for ARCH_USES_GETTIMEOFFSET · 3da6d49e
    Arnd Bergmann 提交于
    We can now select clocksource drivers like ti-32k and CONFIG_OF
    on ancient machines that still use gettimeoffset, and the combination
    results in a link error.
    
    arch/arm/kernel/built-in.o: In function `time_init':
    (.init.text+0xc28): undefined reference to `clocksource_probe'
    
    The reason for this is that the Makefile is hidden behind
    CONFIG_ARCH_USES_GETTIMEOFFSET, but the Kconfig file is not, and
    it has shown up just now because the ti-32k driver was added
    and can be selected using COMPILE_TEST on all platforms.
    
    This patch hides the Kconfig menu in CONFIG_ARCH_USES_GETTIMEOFFSET
    as well.
