Subject: [PATCH 05/12] swiotlb: pass a gfp_mask argument to swiotlb_init_late
Date: Tue, 1 Mar 2022 12:53:04 +0200 [thread overview]
Message-ID: <20220301105311.885699-6-hch@lst.de> (raw)
In-Reply-To: <20220301105311.885699-1-hch@lst.de>
Let the caller chose a zone to allocate from. This will be used
later on by the xen-swiotlb initialization on arm.
Signed-off-by: Christoph Hellwig <hch@lst.de>
