Ok, I will test the ltp syscall test.
With this changes, the issue I mentioned should be fixed. But we still
use mmap2 syscall for ILP32 application when we pass the offset instead
of page offset. Is it correct?

I don't remember. It's probably not important whether we have the shift
in there, as long as it's independent of the actual kernel page size and
user space and kernel agree on the calling conventions.

Well. I am ok with where to shift the pages size because we get the same
result. I was just thinking if we should get rid of the name of mmap2 in our
ILP32 porting. Actually, it is mmap but we name it as mmap2. User may confused
if they do not know the implementations.

This is what generic unistd.h does. If you want to change it, you'd
change each arch that uses generic unistd.h.
