[PATCH v2 04/25] cpu: Annotate static information into meminspect
From: Mukesh Ojha
Date: Tue Mar 10 2026 - 16:18:57 EST
From: Eugen Hristev <eugen.hristev@xxxxxxxxxx>
Annotate vital static information into memory inspection table:
- __cpu_present_mask
- __cpu_online_mask
- __cpu_possible_mask
- __cpu_active_mask
Information on these annotated variables is stored in a dedicated
meminspect section.
