Function copy_segment_data 

unsafe fn copy_segment_data(
    addr_space: &AddressSpace,
    phdr: &ElfPhdr,
    elf: &[u8],
)

Copies an ELF segment into the process’s address space

Safety

The caller must ensure all the following things:

• p_vaddr to p_vaddr + p_filesz needs to be fully mapped in addr_space
• No references/pointers to the target frames should exist and no other CPU should be able to concurrently operate on this data
