++/* 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.
