    Subject[PATCH 1/4] ARM: export read_current_timer
    Date
    read_current_timer is used in the get_cycles() function when
    ARM_ARCH_TIMER is set, and that function can be inlined into
    driver modules, so we should export the function to avoid
    errors like

    ERROR: "read_current_timer" [drivers/video/udlfb.ko] undefined!
    ERROR: "read_current_timer" [crypto/tcrypt.ko] undefined!
