U64_MAX is not in include/vdso/limits.h, although that isn't noticed on x86 because x86 includes include/linux/limits.h indirectly. However powerpc is more selective, resulting in the following build error:
In file included from <command-line>: lib/vdso/gettimeofday.c: In function 'vdso_calc_ns': lib/vdso/gettimeofday.c:11:33: error: 'U64_MAX' undeclared 11 | # define VDSO_DELTA_MASK(vd) U64_MAX | ^~~~~~~
Use ULLONG_MAX instead which will work just as well and is in include/vdso/limits.h.
