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 !

I believe MAP_UNINITIALIZED is only used by the Linux kernel for noMMU cases, so the ARC definition was wrong. 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?

best regards Waldemar
