From c416aee7e7d04fec2d2d30786b3c8393108b85d2 Mon Sep 17 00:00:00 2001 From: Illia Ostapyshyn Date: Mon, 27 Apr 2026 16:24:47 +0200 Subject: [PATCH] scripts/gdb: mm: cast untyped symbols in x86_page_ops 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.
