Yes, that's right.

The kernel is never going to change. 

There is both a correctness and performance issue.

You can't expect MAP_FIXED to work correctly and quickly unless you follow
certain per-architecture rules.

In this case it's correct to map at intervals of SHMLBA.

This still impacts parisc, sh, mips, arm and sparc.

I'd accept a patch that does that.
