CONFIG_GENERIC_GETTIMEOFDAY is a sufficient condition to verify if an architecture implements or not asm/vdso/clocksource.h. The current implementation wrongly assumes that the same is true for the config option CONFIG_ARCH_CLOCKSOURCE_DATA. This results in a series of building errors on ia64/sparc/sparc64 like the one below: 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 <asm/vdso/clocksource.h> | ^~~~~~~~~~~~~~~~~~~~~~~~ Fix the issue removing the unneeded config condition.
