Subject: mm/alloc_tag: add the ARCH_NEEDS_WEAK_PER_CPU macro when statically defining the percpu variable alloc_tag_counters
Date: Thu, 29 May 2025 15:35:37 +0800

Recently discovered this entry while checking kallsyms on ARM64:
ffff800083e509c0 D _shared_alloc_tag

If ARCH_NEEDS_WEAK_PER_CPU is not defined,there's no need to statically
define the percpu variable alloc_tag_counters.

Therefore, add the relevant macro guards at the appropriate location.
