Subject: ipc/msg.c "cleanup" breaks fakeroot on Alpha

Hi,

this hunk

commit 5a06a363ef48444186f18095ae1b932dddbbfa89
Author: Ingo Molnar <mingo@...e.hu>
Date:   Sun Jul 30 03:04:11 2006 -0700

    [PATCH] ipc/msg.c: clean up coding style
    
    Clean up ipc/msg.c to conform to Documentation/CodingStyle.  (before it was
    an inconsistent hodepodge of various coding styles)
    
    Verified that the before/after .o's are identical.

breaks fakeroot on Alpha (variously hangs or oopses). Backing it out
of 2.6.19-rc4 fixes the issue. Is it possible that this change (which
clearly does change semantics) was made in error?
