From 27a0918d4b701d4825e191448e44b9f14dc0a3b3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 5 May 2025 10:11:22 +0200 Subject: [PATCH] scsi: make ppa depend on !HIGHMEM This is one of the last drivers depending on the block layer bounce buffering code. Restrict it to run on non-highmem configs so that the bounce buffering code can be removed.
