Subject: scripts/gdb: mm: cast untyped symbols in x86_page_ops
Date: Mon, 27 Apr 2026 16:24:47 +0200

The symbols phys_base, _text, and _end, used in x86_page_ops are either
defined in assembly or implicitly by the linker.  Thus, they lack type
information and cause a conversion error after gdb.parse_and_eval. 
Explicitly cast these expressions to unsigned long.
