I think I know what this is.  On any arch where sizeof(int) != 
sizeof(void *) the kernel version on my site would oops.  The kernel you 
tested was one where I was in the process of adding kzalloc() to slab.c 
so that driver backports would be a bit less painful in the future. 
However, I missed adding the function prototype to the include files. 
This resulted in a lot of "assignment makes pointer from integer without 
a cast" errors anywhere kzalloc was used.  Well, on 64bit arches, you 
can't make a full pointer from an integer.  So, I'm thinking that the 
oops is the result of a partial conversion from a 32bit int to a 64bit 
pointer, even though kzalloc actually returned a 64bit pointer anyway. 
The attached patch should be able to be dropped into the existing srpm 
in place of the patch with the same name and a rebuild should then solve 
the problem, although in the process of creating this patch I had to 
move it from the 2700 section of the patch list down to the 10002 
position because it touches things added after the infiniband code.
