    drivers/char/Kconfig:

    config HPET_MMAP
    bool "Allow mmap of HPET"
    default y
    depends on HPET
    help
    If you say Y here, user applications will be able to mmap
    the HPET registers.

    In some hardware implementations, the page containing HPET
    registers may also contain other things that shouldn't be
    exposed to the user. If this applies to your hardware,
    say N here.
