Hi,
I've hit boot problems in next-20130204 on Meta:
META213-Thread0 DSP [LogF] kobject (4fc03980): tried to init an initialized object, something is seriously wrong.

I've bisected it to the following commit:
commit 95a05b428cc675694321c8f762591984f3fd2b1e

slab: Common constants for kmalloc boundaries
Standardize the constants that describe the smallest and largest
object kept in the kmalloc arrays for SLAB and SLUB.
Differentiate between the maximum size for which a slab cache is used
(KMALLOC_MAX_CACHE_SIZE) and the maximum allocatable size
(KMALLOC_MAX_SIZE, KMALLOC_MAX_ORDER).

Any ideas what could be going on here?
This commit merged with the metag for-next branch fails, but
the previous commit merged with the metag for-next branch
doesn't fail.
