Please, ignore this patch.
There is a 31-bit counter in CPU local timers; however,
FRC (free running down-counters) of CPU local timers is
32-bit. Thus, there is no need to fix it.

The Samsung's Multi Core Timer (MCT) module includes two main blocks, the
global timer and CPU local timers. The global timer is a 64-bit free running
up-counter and can generate 4 interrupts when the counter reaches one of the
-four preset counter values. The CPU local timers are 32-bit free running
+four preset counter values. The CPU local timers are 31-bit free running
down-counters and generate an interrupt when the counter expires. There is
one CPU local timer instantiated in MCT for every CPU in the system.
