See:

[PATCH] xfs: call roundup_64() to calculate the min_logblks

on the xfs list:

From: Jie Liu <jeff.liu@xxxxxxxxxx>

Replace roundup() with roundup_64() as we calculate min_logblks
with 64-bit divisions. Hence, call roundup() will cause the
following error while compiling a 32-bit kernel:

fs/built-in.o: In function `xfs_log_calc_minimum_size':
fs/xfs/xfs_log_rlimit.c:140: undefined reference to `__udivdi3'
