The patch titled Subject: kernel/extable.c: use address-of operator on section symbols has been removed from the -mm tree. Its filename was kernel-extable-use-address-of-operator-on-section-symbols.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Nathan Chancellor <natechancellor@xxxxxxxxx> Subject: kernel/extable.c: use address-of operator on section symbols Clang warns: ../kernel/extable.c:37:52: warning: array comparison always evaluates to a constant [-Wtautological-compare] if (main_extable_sort_needed && __stop___ex_table > __start___ex_table) { ^ 1 warning generated. These are not true arrays, they are linker defined symbols, which are just addresses. Using the address of operator silences the warning and does not change the resulting assembly with either clang/ld.lld or gcc/ld (tested with diff + objdump -Dr).
