Series sysctl: Move sysctls to their respective subsystems (second batch) | expand

Commit Message

Joel Granados May 9, 2025, 12:54 p.m. UTC 
Move the randomize_va_space variable together with all its sysctl table
elements into memory.c. Register it to the "kernel" directory by
adding it to the subsys initialization calls

This is part of a greater effort to move ctl tables into their
respective subsystems which will reduce the merge conflicts in
kernel/sysctl.c.
