-/* When trying to map /dev/mem with offset 0xFFFFF000 on the ARM platform, mmap
- * returns -EOVERFLOW.
- *
- * Since off_t is defined as a long int and the sign bit is set in the address,
- * the shift operation shifts in ones instead of zeroes
- * from the left. This results the offset sent to the kernel function becomes
- * 0xFFFFFFFF instead of 0x000FFFFF with MMAP2_PAGE_SHIFT set to 12.
