Subject: [PATCH] vdso: Fix powerpc build U64_MAX undeclared error
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.
Reported-by: Stephen Rothwell <sfr@...b.auug.org.au>
Closes: https://lore.kernel.org/all/20240409124905.6816db37@canb.auug.org.au/
Fixes: c8e3a8b6f2e6 ("vdso: Consolidate vdso_calc_delta()")
