no, 2.4 will break, because shmctl will try to fixup structs, which
don't need fixing. Please look at the code in sys_parisc.c

we only have new structs in the sense of ipc/*.c. That old stuff
is older x86 stuff, we never had. The only problem is, that we
had some broken structs, which weren't working on 64bit kernel, because
the alignment was broken.

so why no just use the same way, I changed it in 2.4 ?
