linux-next: build failure after merge of the ftrace tree

Hi all,

After merging the ftrace tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

kernel/trace/trace_syscalls.c: In function 'print_syscall_enter':
kernel/trace/trace_syscalls.c:267:48: error: 'TRACE_ITER_VERBOSE' undeclared (first use in this function); did you mean 'TRACE_ITER_VERBOSE_BIT'?
267 | if (!tr || !(tr->trace_flags & TRACE_ITER_VERBOSE))
| ^~~~~~~~~~~~~~~~~~
| TRACE_ITER_VERBOSE_BIT
kernel/trace/trace_syscalls.c:267:48: note: each undeclared identifier is reported only once for each function it appears in

Caused by commit

64b627c8da9a ("tracing: Add parsing of flags to the sys_enter_openat trace event")

interacting with commit

bbec8e28cac5 ("tracing: Allow tracer to add more than 32 options")

which should have been fixed up in commit

2021eabbdb41 ("Merge probes/for-next")

I have used the ftrace tree from next-20251105 for today.
