Yes this is nicer (sorry must have missed the patch), even though this bit 
unnecessary:
<snip, line 228 in above file:>
         unsigned int *cpu = info;

         BUG_ON (*cpu != smp_processor_id());
<snip>

If gcc optimizes the "cpu" into a register then fine but if not, it would 
be IMHO preferable to use this instead:

         BUG_ON(*(unsigned int *)info != smp_processor_id());

Why not push now considering 2.5.9 isn't out yet?

Considering the current bitkeeper tree on bkbits does not compile on ia32 
UP at all by any close margin, the more fixes that go in now the better...

I spent two hours this morning try to get it to compile on UP but I got 
stuck in arch/i386/kernel/msr.c: gcc complains about cpu_data not being 
defined even though the right include file is included. Obviously a nasty 
out of scope included headers interdependency which I haven't managed to see...

And adding to that that the ia32 SMP compiled kernel doesn't manage to boot 
on my machine yet (as of this morning, containing up to IDE39 patch still 
didn't boot due to hanging after detecting hda but before hdc as I have 
reported before).

Releasing 2.5.9 in current state would not be too useful for people like me 
who experience the ide problems...

Best regards,

Anton
