#     gcc-plugins/stackleak: Use noinstr in favor of notrace
#     
#     While the stackleak plugin was already using notrace, objtool is now a
#     bit more picky.  Update the notrace uses to noinstr.  Silences the
#     following objtool warnings when building with:
#     
#     CONFIG_DEBUG_ENTRY=y
#     CONFIG_STACK_VALIDATION=y
#     CONFIG_VMLINUX_VALIDATION=y
#     CONFIG_GCC_PLUGIN_STACKLEAK=y
#     
#       vmlinux.o: warning: objtool: do_syscall_64()+0x9: call to stackleak_track_stack() leaves .noinstr.text section
#       vmlinux.o: warning: objtool: do_int80_syscall_32()+0x9: call to stackleak_track_stack() leaves .noinstr.text section
#       vmlinux.o: warning: objtool: exc_general_protection()+0x22: call to stackleak_track_stack() leaves .noinstr.text section
#       vmlinux.o: warning: objtool: fixup_bad_iret()+0x20: call to stackleak_track_stack() leaves .noinstr.text section
#       vmlinux.o: warning: objtool: do_machine_check()+0x27: call to stackleak_track_stack() leaves .noinstr.text section
#       vmlinux.o: warning: objtool: .text+0x5346e: call to stackleak_erase() leaves .noinstr.text section
#       vmlinux.o: warning: objtool: .entry.text+0x143: call to stackleak_erase() leaves .noinstr.text section
#       vmlinux.o: warning: objtool: .entry.text+0x10eb: call to stackleak_erase() leaves .noinstr.text section
#       vmlinux.o: warning: objtool: .entry.text+0x17f9: call to stackleak_erase() leaves .noinstr.text section
#     
#     Note that the plugin's addition of calls to stackleak_track_stack() from
#     noinstr functions is expected to be safe, as it isn't runtime
#     instrumentation and is self-contained.
