True, from some perspective.

But you have to admit the pointer math gets real ugly if we declare
them in that way. :-)

Whoever changed this:

+u8 cpu_2_logical_apicid[NR_CPUS] = { [0 ... NR_CPUS-1] = BAD_APICID };

needs to grep for all occurences through subarch, etc. eg:

There may be other similar problems, but this should fix up those at least.

Have hit this a few times already in -mm2. Always happens under reasonably 
heavy disk load on an ext3 mount. I've gone back to -mm1 since just about all 
compile jobs fail on this kernel. 

Here's my oops:

Unable to handle kernel NULL pointer dereference at virtual address 00000014

OK, bad bug.  This should fix it.
