From cf3cd4e3b32d3cf7b37e49ad8e0ea07d44ec25a4 Mon Sep 17 00:00:00 2001 From: Muhammad Usama Anjum Date: Thu, 30 Jul 2026 10:45:00 +0100 Subject: [PATCH] parisc: sba_iommu: Remove dead DEBUG_DMB_TRAP code DEBUG_DMB_TRAP is unconditionally undefined, so the guarded declarations and calls can never be built. The declared iterate_pages() and set_data_memory_break() functions also have no definitions in the tree; removing the #undef would therefore leave unresolved references. Remove the unused option and its guarded code.
