[PATCH] MAINTAINERS: add an entry for MEMORY MANAGEMENT - MEMORY MAP

[PATCH] MAINTAINERS: add an entry for MEMORY MANAGEMENT - MEMORY MAP

[Mike Rapoport (Microsoft)]

Split out files related to SPARSE and SPARSE_VMEMMAP management from
MEMORY MANAGEMENT - CORE into a dedicated entry.

Also include architecture specific sparsemem.h headers, pfn_to_page() and
page_to_pfn() conversions and Documentation/mm/memory-model.rst.

Muchun, who did a lot of work cleaning up SPARSE_VMEMMAP and extending
vmemmap optimization, volunteered to help with the maintenance.

David and I will continue to look after that part of the mm subsystem.
