Subject: mm/swap: fix swap_cluster_lock() !CONFIG_SWAP stub signature mismatch
Date: Fri, 17 Jul 2026 15:11:04 +0800

The !CONFIG_SWAP stub for swap_cluster_lock() has mismatched prototype: it
has an extra unused irq argument and uses pgoff_t instead of unsigned long
for offset.  All callers are under CONFIG_SWAP so the extra parameter is
dead.

Delete the unused stub function entirely.
