Subject: CMA: use MIGRATE_SYNC in alloc_contig_range()
Before commit 'mm, compaction: embed migration mode in compact_control'
from David is merged, alloc_contig_range() used sync migration,
instead of sync_light migration. This doesn't break anything currently
because page isolation doesn't have any difference with sync and
sync_light, but it could in the future, so change back as it was.
And pass cc->mode to migrate_pages(), instead of passing MIGRATE_SYNC
to migrate_pages().
