[PATCH v2 13/25] mm/init-mm: Annotate static information into meminspect

[Mukesh Ojha]

From: Eugen Hristev <eugen.hristev@xxxxxxxxxx>

Annotate vital static information into inspection table:
 - init_mm
 - swapper_pg_dir
 - _sinittext
 - _einittext
 - _end
 - _text
 - _stext
 - _etext

Information on these variables is stored into dedicated meminspect
section.
