[PATCH 0/5] mm, slab: Make kmalloc_info[] contain all types of names

[Pengfei Li <lpf.vector@gmail.com>]

There are three types of kmalloc, KMALLOC_NORMAL, KMALLOC_RECLAIM
and KMALLOC_DMA.

The name of KMALLOC_NORMAL is contained in kmalloc_info[].name,
but the names of KMALLOC_RECLAIM and KMALLOC_DMA are dynamically
generated by kmalloc_cache_name().

Patch1 predefines the names of all types of kmalloc to save
the time spent dynamically generating names.

The other 4 patches did some cleanup work.

These changes make sense, and the time spent by new_kmalloc_cache()
has been reduced by approximately 36.3%.
