Daniel Thompson d07ce4e32a kdb: Avoid array subscript warnings on non-SMP builds ... Recent versions of gcc (reported on gcc-7.4) issue array subscript warnings for builds where SMP is not enabled. kernel/debug/debug_core.c: In function 'kdb_dump_stack_on_cpu': kernel/debug/debug_core.c:452:17: warning: array subscript is outside array +bounds [-Warray-bounds] if (!(kgdb_info[cpu].exception_state & DCPU_IS_SLAVE)) { ~~~~~~~~~^~~~~ kernel/debug/debug_core.c:469:33: warning: array subscript is outside array +bounds [-Warray-bounds] kgdb_info[cpu].exception_state |= DCPU_WANT_BT; kernel/debug/debug_core.c:470:18: warning: array subscript is outside array +bounds [-Warray-bounds] while (kgdb_info[cpu].exception_state & DCPU_WANT_BT) There is no bug here but there is scope to improve the code generation for non-SMP systems (whilst also silencing the warning).
