[LTP] madvise07.c:72: FAIL: Did not receive SIGBUS

[Li Wang]

Hi,

I'm trying to run ltp on upstream kernel-4.10.0-rc7, and found that
madvise07 always failing with no SIGBUS received when mmap the PRIVATE
memory. I hope to know if there're some relevant stuff about this
issue.
Any discussion or document for that?
