    Subject[PATCH 5.19 0064/1157] parisc: Drop pa_swapper_pg_lock spinlock
    Date
    From: Helge Deller <deller@gmx.de>

    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.
