mm, slab: shorten kmalloc cache names for large sizes
Kmalloc cache names can get quite long for large object sizes, when the
sizes are expressed in bytes. Use 'k' and 'M' prefixes to make the names
as short as possible e.g. in /proc/slabinfo. This works, as we mostly
use power-of-two sizes, with exceptions only below 1k.
Example: 'kmalloc-4194304' becomes 'kmalloc-4M'
