Cover letter [Qemu-devel] [PATCH 0/2] ide: fix GPCMD_GET_CONFIGURATION for correct DVD-ROM emulation

The following patch series complements "Partial IDE DVD emulation" which was added in revision 1.66 of ide.c and that was generating the following timeouts for OpenSolaris guests when trying to access the ATAPI CD-ROM (during installation for example):

  WARNING: /pci@0,0/pci-ide@1,1/ide@1 (ata1);
          timeout: abort request, target=0 lun=0
  WARNING: /pci@0,0/pci-ide@1,1/ide@1 (ata1):
          timeout: abort device, target=0 lun=0
  WARNING: /pci@0,0/pci-ide@1,1/ide@1 (ata1):
          timeout: reset target, target=0 lun=0
  WARNING: /pci@0,0/pci-ide@1,1/ide@1 (ata1):
          timeout: reset bus, target=0 lun=0

It has been tested to fix the problem and not to introduce any regression with several releases of Linux, BSD (FreeBSD, OpenBSD, NetBSD and DragonflyBSD), Windows 2K and OpenSolaris (Nexenta, Indiana, SXDE) and Solaris 10 guests in x86 (32bit) and amd64 (64bit) hosts and to match exact responses when compared to responses received by physical SATA and ATAPI DVD-ROM devices.

Patch 1/2: fixes GET_CONFIGURATION to allow OpenSolaris CD-ROM access Patch 2/2: uses DVD-ROM as model name for INQUIRY and IDENTIFY DEVICE
