From 7d17e84bb8356b1d9f4402dd82a0e270a3d59a4f Mon Sep 17 00:00:00 2001 From: Daniel De Graaf Date: Wed, 14 Dec 2011 15:12:11 -0500 Subject: xen/grant-table: Support mappings required by blkback Add support for mappings without GNTMAP_contains_pte. This was not supported because the unmap operation assumed that this flag was being used; adding a parameter to the unmap operation to allow the PTE clearing to be disabled is sufficient to make unmap capable of supporting either mapping type.
