I believe MAP_UNINITIALIZED is only used by the Linux kernel for

Is it really a semantically change, if Linux kernel ignores it for
MMU targets?
May be a better commit log like the attached clarifies it?

Hi,
I would like to push attached patch next week.
Any veto?
So it seems there is code consolidation and additionally there's seems to be
a semantical change to ldso mmap().
Assuming __ARCH_USE_MMU__ is true for say ARC, now we have
_MAP_UNINITIALIZED == 0 vs. before MAP_UNINITIALIZED == 0x4000000.
So we won't be zero init ldso anon mmaps - which could be functionally OK,
but I think better to split it out as a seperate patch just to call this out
!
