the question about PT_DYNAMIC's p_offset value in elf file for mips platform

The PT_DYNAMIC segment includes more than just the .dynamic section.  It 
also includes sections like .hash, .dynsym etc.  Hence the segment 
starts at the lowest offset of all of these sections, which in this case 
is the .hash section.

If you have a look at the section to segment mapping output from readelf:

You can see the relationship between segments and sections.
