Subject: percpu: repurpose __percpu tag as a named address space qualifier
Date: Sun, 8 Dec 2024 21:45:20 +0100
The patch introduces __percpu_qual define and repurposes __percpu tag as a
named address space qualifier using the new define.
Arches can now conditionally define __percpu_qual as their named address
space qualifier for percpu variables.
