  • ca214e2c1   vdso: Fix clocksource.h macro detection ... Browse Code »

    CONFIG_GENERIC_GETTIMEOFDAY is a sufficient condition to verify if an
    architecture implements asm/vdso/clocksource.h or not. The current
    implementation wrongly assumes that the same is true for the config
    option CONFIG_ARCH_CLOCKSOURCE_DATA.

    This results in a series of build errors on ia64/sparc/sparc64 like this:

    In file included from ./include/linux/clocksource.h:31,
    from ./include/linux/clockchips.h:14,
    from ./include/linux/tick.h:8,
    from fs/proc/stat.c:15:
    ./include/vdso/clocksource.h:9:10: fatal error: asm/vdso/clocksource.h:
    No such file or directory
    9 | #include
    | ^~~~~~~~~~~~~~~~~~~~~~~~

    Fix the issue removing the unneeded config condition.

    The vDSO library should only include the necessary headers required for
    a userspace library (UAPI and a minimal set of kernel headers). To make
    this possible it is necessary to isolate from the kernel headers the
    common parts that are strictly necessary to build the library.

    Split clocksource.h into linux and common headers to make the latter
    suitable for inclusion in the vDSO library.
