I have made a tool to parse the kernel that does not pre-process the
source.  That means that my parser tries to parse all the code, including
code in the #else branch or code that is not often compiled because the
driver is not very used (or not used at all).  So, my parser sometimes
reports parse error not originally detected by gcc.  Here is my (first)
patch.

may eat all available system memory under 4G, then the system may fail to

The Via VT3351 APIC does not play well with MSI and unleashes a flood
of APIC errors when MSI is used to deliver interrupts.  The problem
was recently exposed when the atl1 network device driver, which enables
MSI by default, stimulated APIC errors on an Asus M2V mainboard, which
employs the Via VT3351.
See http://bugzilla.kernel.org/show_bug.cgi?id=8472 for additional

Wolfgang gets:

 PCI: Cannot allocate resource region 0 of device 0000:00:04.0
 PCI: Error while updating region 0000:00:04.0/0 (a8008000 != fec08000)

Note that the BAR seems to have high address bits hardwired to fec00000.
And device 0000:00:04.0 is

 00:04.0 System peripheral: Siemens Nixdorf AG FSC Multiprocessor Interrupt Controller (rev 02)

I'd guess that when we try to reassign this resource, PCI interrupts might
just stop working. This could explain SCSI timeouts and other weird things.

We need this patch in ASAP.  Patch fixes the mysterious hang that remained
on some particular configurations with lockdep on after the first fix that
moved the #idef CONFIG_SLUB_DEBUG to the right location.  See
http://marc.info/?t=117963072300001&r=1&w=2

The kmem_cache_node cache is very special because it is needed for NUMA
bootstrap.  Under certain conditions (like for example if lockdep is
enabled and significantly increases the size of spinlock_t) the structure
may become exactly the size as one of the larger caches in the kmalloc
array.

That early during bootstrap we cannot perform merging properly.  The unique
id for the kmem_cache_node cache will match one of the kmalloc array.
Sysfs will complain about a duplicate directory entry.  All of this occurs
while the console is not yet fully operational.  Thus boot may appear to be
silently failing.

The kmem_cache_node cache is very special.  During early boostrap the main
allocation function is not operational yet and so we have to run our own
small special alloc function during early boot.  It is also special in that
it is never freed.

We really do not want any merging on that cache.  Set the refcount -1 and
forbid merging of slabs that have a negative refcount.
