6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andrea Righi <arighi@xxxxxxxxxx>
commit 3c7d51b0d29954c40ea3a097e0ec7884b4344331 upstream.
In UP systems p->migration_disabled is not available. Fix this by using
the portable helper is_migration_disabled(p).
Fixes: e9fe182772dc ("sched_ext: selftests/dsp_local_on: Fix sporadic failures")
