[PATCH 5.19 0064/1157] parisc: Drop pa_swapper_pg_lock spinlock
From: Greg Kroah-Hartman
Date: Mon Aug 15 2022 - 18:03:37 EST
From: Helge Deller <deller@xxxxxx>
commit 3fbc9a7de0564c55d8a9584c9cd2c9dfe6bd6d43 upstream.
This spinlock was dropped with commit b7795074a046 ("parisc: Optimize
per-pagetable spinlocks") in kernel v5.12.
Remove it to silence a sparse warning.
