리눅스 메모리 보다가 계속 영어로 0x7ffffb78 부분을 말하는 부분이 있습니다만...

The NOP block technique can be used o increase chances of a successful
exploitation. The preferred instruction for NOP operation in Power/CBEA
based processors is oril r0,r0,0 (0x60000000). However, the instruction
mr r31,r31 (0x7ffffb78) is used in order to avoid zeros.
With this information, a moderated guess of heap address that pos-
sibly will contain a NOP instruction from the NOP block can be done
(0x10011808)
0x7ffffb78부분은 코드 영역인가요? 코드 영역의 NOP??
도대체 뭔지ㅠㅠ
