Several of the nvlist functions may perform allocations larger than the 32k warning threshold. Convert them to use vmem_alloc() so the best allocator is used. Commitefcd79aretired KM_NODEBUG which was used to suppress large allocation warnings. Concurrently the large allocation warning threshold was increased from 8k to 32k. The goal was to identify the remaining locations, such as this one, where the allocation can be larger than 32k. This patch is expected fine tuning resulting for the kmem-rework changes, see commit6e9710f. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #3057 Closes #3079 Closes #3081
