ACPI: create CONFIG_ACPI_DEBUG_FUNC_TRACE
Split ACPI_DEBUG into function trace enabled and not enabled.
Function trace is most of the ACPI_DEBUG costs, but is
not much of use for kernel ACPI debugging.
Size of kernel image increased on test compile:
+ 48k (Full ACPI_DEBUG)
+ 35k (ACPI_DEBUG with function trace compiled out)
Performance without function trace is also much better.
Also remove ACPI_LV_DEBUG_OBJECT from default debug level as
a lot vendors let Store (value, debug) in their code and this
might confuse users when it pops up in syslog.

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.

It makes sense to allow the colon as a delimiting character without
explicitly having to set it through the 'delim' variable as there can be

e1000_close always calls netif_poll_disable.
netif_poll_enable can only be called safely if no polls have been

[ARM] Fix stacktrace FP range checking
Fix an oops in the stacktrace code, caused by improper range checking.
We subtract 12 off 'fp' before testing to see if it's below the low
bound. However, if 'fp' were zero before, it becomes a very large
positive number, causing this test to succeed where it should fail.
