a2438700e4 virtio-devices: support event idx for virtio-blk 
Support event idx feature for virtio-blk device.
This feature could improve disk IO performance by suppressing
notifications from guest to host and interrupts from host to
guest, which has been already supported in virtio-net and
vhost-user devices.

To achieve this, virtqueue's event-idx-related API is
leveraged for avail_event field update and needs_notification
check.

Fixes: #6580

c1f18fa634 arch: x86_64: Don't expose TSC deadline timer for MSHV guests 
HV APIC(i.e., synthetic APIC controller exposed by Microsoft Hypervisor)
does not support one-shot operation using a TSC deadline value. Due to
which we see the following backtrace inside the guest when running with
hypervisor-fw/OVMF:

Also, if this feature is exposed guest would not finish booting and get

bc6acb842f block: fix status value size 
As per VirtIO spec 1.2 section 5.2.6, the `status` field is a byte, not
u32. cloud-hypervisor writes an `u32` to guest memory, which
accidentally zeros out the following 3 bytes, and may corrupt guest OS
internal state.

18340d9761 hypervisor: mshv: fine-grained control over translation flags 
The assertion that only code emulation requires GVA to GPA translation
is wrong.

Allow the caller of `translate` to pass in permission flags directly.

Provide a new method `read_memory_flags` so that we can add the EXECUTE
permission flag where necessary.
