x86/amd-iommu: attach devices to pre-allocated domains early
For some devices the ACPI table may define unity map requirements which must me met when the IOMMU is enabled. So we need to attach devices to their domains as early as possible so that these mappings are in place when needed. This patch assigns the domains right after they are allocated. Otherwise this can result in I/O page faults before a driver binds to a device and BIOS is still using it. Cc: stable@kernel.org Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
