  page table structure
• PageTableEntry
  page table entry structure
• UserBuffer

Functions

• translated_byte_buffer
  Create mutable Vec<u8> slice in kernel space from ptr in other address space. NOTICE: the content pointed to by the pointer ptr can cross physical pages.
• translated_ref
  translate a pointer ptr in other address space to a immutable u8 slice in kernel address space. NOTICE: the content pointed to by the pointer ptr cannot cross physical pages, otherwise translated_byte_buffer should be used.
• translated_refmut
  translate a pointer ptr in other address space to a mutable u8 slice in kernel address space. NOTICE: the content pointed to by the pointer ptr cannot cross physical pages, otherwise translated_byte_buffer should be used.
• translated_str
  Create String in kernel address space from u8 Array(end with 0) in other address space
