s390x: fix smp support for kvm
Currently smp support for kvm does not work. Qemu does a kvm run even onsecondary CPUs which dont have a sane state (initial psw == 0)triggering some program faults. Architecturally these cpus are in the stoppedstate, so we should not do the kvm run ioctl. (these CPUs will be started...
tcg: extend max tcg opcodes when using 64-on-32bit
When running a 64 bit guest on a 32 bit host, we tend to use more TCG opsthan on a 64 bit host. Reflect that in the reserved opcode amount constant.

s390x: make kvm exported functions conditional on kvm
We have some helper functions we use to directly invoke KVMfunctionality from device emulation code.
This patch replaces those exported functions with static inlinestubs when not building with KVM enabled....
ahci: Fix non-NCQ accesses for LBA > 16bits
AHCI provides two ways of reading/writing data:
1) NCQ 2) ATA commands with the LBA in the command FIS
In the second code path, we didn't handle any LBAs that were bigger than16 bits, so whenever a guest that used high LBA numbers wanted to access...
block: Remove type hint, it's guest matter, doesn't belong here
No users of bdrv_get_type_hint() left. bdrv_set_type_hint() can makethe media removable by side effect. Make that explicit.

blockdev: Store -drive option media in DriveInfo
DriveInfo is closely tied to -drive, and like -drive, it mixesinformation about host and guest part of the block device. UnlikeDriveInfo, BlockDriverState should be about the host part only.
One of the remaining guest bits there is the "type hint". -drive...
block QMP: Deprecate query-block's "type", drop info block's "type="
query-block's specification documents response member "type" withvalues "hd", "cdrom", "floppy", "unknown".
Its value is unreliable: a block device used as floppy has type"floppy" if created with if=floppy, but type "hd" if created with...
defaults: ide-cd, ide-hd and scsi-cd devices suppress default CD-ROM
ide-hd has to suppress the default CD-ROM, or else you can't put oneon secondary master without -nodefaults.
Unlike legacy scsi-disk, scsi-cd suppresses default CD-ROM.

scsi: Split qdev "scsi-disk" into "scsi-hd" and "scsi-cd"
A "scsi-disk" is either a hard disk or a CD-ROM, depending on theassociated BlockDriverState's type hint. Unclean; disk vs. CD belongsto the guest part, not the host part.
Have separate qdevs "scsi-hd" and "scsi-cd" to model disk vs. CD in...
