Re: [PATCH 6/8] mm/bootmem_info: stop marking mem_section_usage as MIX_SECTION_INFO

We never free the ms->usage data for boot memory sections (see
section_deactivate()). And to identify whether ms->usage was allocated
from memblock, we simply identify it by looking at PG_reserved.

Yep, PageReserved() is already enough to tell that case apart :)

Consequently, there is no need to mark ms->usage as MIX_SECTION_INFO.
Let's just stop doing that.

Right, MIX_SECTION_INFO doesn't add much here. For ms->usage, removal
code doesn't use MIX_SECTION_INFO at all :)
