[IA64] bug in ldscript (mainstream)
Occasionally, in mainstream number of fsys entries is even.
In OpenVZ it is odd and we get misaligned kernel image,
which does not boot.

Is it a typo on "fsys entries is even"?
If not, then this change log is misleading. It is the instruction
patch list of FSYS_RETURN that can potentially cause other data
structures to be out of alignment. And number of FSYS_RETURN call
site will not necessarily match number of fsys entry.

Otherwise, the patch looks fine to me.
