Question on virtual memory layout: lowmem with memory hole

Hello, While checking with memory hole configuration on OMAP3/TI816X (passing mem=x@y), I see that the whole range from memory start till last bank including the hole is labelled as 'lowmem' when kernel prints Virtual kernel memory layout during boot. E.g., on OMAP3 with mem=32M@0x8000
