+The patch 0003-fix-ktime-get-seconds-prototype.patch changed get_seconds() to ktime_get_seconds(),
+but did not account for the change in prototype, i.e., unsigned long to time64_t. As a result, the armhf
+module won't install for lack of a dependency on __aeabi_ldivmod.
+
+The solution is to type case ktime_get_seconds() to 'unsigned long' where ever integer division is
+performed.
