Subject: lib/Kconfig.debug: make DEBUG_FORCE_WEAK_PER_CPU depend on S390||ALPHA
Date: Mon Aug 10 08:50:56 PM PDT 2026

CONFIG_DEBUG_FORCE_WEAK_PER_CPU appears to be alpha-specific.  The Kconfig
help text says s390 can need it also, but the comment in percpu-defs.h
only mentions alpha.  The original commit 7c756e6e19e7 ("percpu: implement
optional weak percpu definitions") mentions both alpha and s390.

All quite mysterious and perhaps this feature is no longer needed.

However x86_64 allmodconfig enables it, and because mm/alloc_tag.c
requires !DEBUG_FORCE_WEAK_PER_CPU (another mystery), alloc_tag isn't
getting allmodconfig build coverage.

Adding `depends on S390||ALPHA' fixes this.
