096434fea1 hw/ufs: Modify lu.c to share codes with SCSI subsystem
This patch removes the code that ufs-lu was duplicating from
scsi-hd and allows them to share code.

It makes ufs-lu have a virtual scsi-bus and scsi-hd internally.
This allows scsi related commands to be passed thorugh to the scsi-hd.
The query request and nop command work the same as the existing logic.

Well-known lus do not have a virtual scsi-bus and scsi-hd, and
handle the necessary scsi commands by emulating them directly.

NR_IOBUS_DEVS was increased to 200 in Linux 2.6.34.  By Linux 3.5 it had
increased to 1000 and later ioeventfds were changed to not count against
the limit.  But the earlier limit of 200 would already be enough for
kvm_check_many_ioeventfds() to be true, so remove the check.

This was introduced in KVM in Linux 3.5, we can require it unconditionally

it so check it only in x86, the only architecture that ever had MSI injection
but not KVM_CAP_SIGNAL_MSI.

ARM uses it to detect the presence of the ITS emulation in the kernel,
introduced in Linux 4.8.  Assume that it's there and possibly fail when
realizing the arm-its-kvm device.

d4eb503808 vhost-user: Fix protocol feature bit conflict
The VHOST_USER_PROTOCOL_F_XEN_MMAP feature bit was defined in
f21e95ee97, which has been part of qemu's 8.1.0 release.  However, it
seems it was never added to qemu's code, but it is well possible that it
is already used by different front-ends outside of qemu (i.e., Xen).

VHOST_USER_PROTOCOL_F_SHARED_OBJECT in contrast was added to qemu's code
in 1609476662, but never defined in the vhost-user specification.  As a
consequence, both bits were defined to be 17, which cannot work.

Regardless of whether actual code or the specification should take
precedence, F_XEN_MMAP is already part of a qemu release, while
F_SHARED_OBJECT is not.  Therefore, bump the latter to take number 18
instead of 17, and add this to the specification.

Take the opportunity to add at least a little note on the
VhostUserShared structure to the specification.  This structure is
referenced by the new commands introduced in 1609476662, but was not
defined.

f02a4b8e64 vhost-user: fix lost reconnect
When the vhost-user is reconnecting to the backend, and if the vhost-user fails
at the get_features in vhost_dev_init(), then the reconnect will fail
and it will not be retriggered forever.

The reason is:
When the vhost-user fails at get_features, the vhost_dev_cleanup will be called
immediately.

vhost_dev_cleanup calls 'memset(hdev, 0, sizeof(struct vhost_dev))'.

The reconnect path is:
vhost_user_blk_event
   vhost_user_async_close(.. vhost_user_blk_disconnect ..)
     qemu_chr_fe_set_handlers <----- clear the notifier callback
       schedule vhost_user_async_close_bh

The vhost->vdev is null, so the vhost_user_blk_disconnect will not be
called, then the event fd callback will not be reinstalled.

All vhost-user devices have this issue, including vhost-user-blk/scsi.

With this patch, if the vdev->vdev is null, the fd callback will still
be reinstalled.

40f7062387 hw/isa/piix3: Rename "pic" attribute to "isa_irqs_in"
TYPE_PIIX3_DEVICE doesn't instantiate a PIC since it relies on the board to do
so. The "pic" attribute, however, suggests that there is one. Rename the
attribute to reflect that it represents ISA interrupt lines. Use the same naming
convention as in the VIA south bridges as well as in TYPE_I82378.
