Hi,
could someone investigate the following build failure on powerpc [1], please?
In file included from /build/reproducible-path/linux-6.16.12/kernel/sched/build_policy.c:64:
/build/reproducible-path/linux-6.16.12/kernel/sched/ext_idle.c: In function ‘is_bpf_migration_disabled’:
/build/reproducible-path/linux-6.16.12/kernel/sched/ext_idle.c:893:14: error: ‘const struct task_struct’ has no member named ‘migration_disabled’
893 | if (p->migration_disabled == 1)
| ^~
/build/reproducible-path/linux-6.16.12/kernel/sched/ext_idle.c:896:25: error: ‘const struct task_struct’ has no member named ‘migration_disabled’

Thanks,
