I just found out that reverting this commit fixes the problem. Any
ideas about why other arches don't encouter the problem?

Modified files:
sys/vm uma.h uma_core.c
Log:
- Remove bogus use of kmem_alloc that was inherited from the old zone
allocator.
- Properly set M_ZERO when talking to the back end page allocators for
non malloc zones. This forces us to zero fill pages when they are first
brought into a cache.
- Properly handle M_ZERO in uma_zalloc_internal. This fixes a problem where
per cpu buckets weren't always getting zeroed.
