Subject: [PATCH 14/29] mm: rename vmap_page_range to map_kernel_range
Date: Tue, 14 Apr 2020 15:13:33 +0200
Message-ID: <20200414131348.444715-15-hch@lst.de> (raw)
In-Reply-To: <20200414131348.444715-1-hch@lst.de>

This matches the map_kernel_range_noflush API.  Also change to pass
a size instead of the end, similar to the noflush version.
