The initial support for virtio-blk-pci IPL devices used a single virt-queue, but
other device types require multiple queues, and for PCI device types this also
requires a per-queue notification offset.
Add a PCI notify field to the VRing struct so that each queue has a unique
notify offset as defined in the virtio spec.

HPPA patches for qemu-v11
A few late fixes for the HPPA architecture for QEMU v11:
- graphics support was broken for 64-bit machines. This series adds
support for VGA graphics for Linux guests
- the various memory ranges were not correctly implemented
- TOC/NMI was not working on 64-bit machines
- minor 64-bit HP-UX boot fixes (but HP-UX 64-bit still crashes)

Remove the duplicate definitions from hw/s390x/ipl.h and pc-bios/s390-ccw/iplb.h
and add a shared definition. The new definition is an enum to enforce default
handling in switches.
Because the IPL type is determined by the IPLB, and because an IPLB is not
strictly necessary, the IPL type is set to a default value if not otherwise
specified. A default IPL type is required so future functionality may add
IPL new bus and/or device types that dictate specific behavior during IPL.

HP-PARISC 715 machine with NCR710 SCSI chip
This series adds a new emulation for a HP PA-RISC 715/64 model,
as descrived here: https://www.openpa.net/systems/hp-9000_715.html.
That machine has no PCI bus and instead uses a "LASI" chip which has built-in
NCR 53c710 SCSI and i82596 network chips. Compared to the other already
emulated machines B160L and C3700, this machine should be able to support older
operating systems like HP-UX 9 as well.
The QEMU project participated in the Google Summer of Code 2025 program by
"Implementing LASI Network Card and NCR 710 SCSI Controller Device Models", and
Soumyajyotii Ssarkar stepped up to develop those drivers.
This patch series includes the code for the NCR710 SCSI controller,
the network code will follow in later patch series.

We can see that the instruction at 0x1e3 is a far jmp through the GDT.
However, the GDT is not 8 byte aligned, the base is 0xc02b4.
Intel processors follow the LOCK semantics to set the accessed flag of the
segment descriptor when loading a segment descriptor. If the the segment
descriptor crosses two cache line, it causes split lock.
Fix it by aligning the GDT on 8 bytes, so that segment descriptor cannot
span two cache lines.
