  6. target/s390x: Use a 16-bit immediate in VREP 

    Unlike most other instructions that contain an immediate element index,
VREP's one is 16-bit, and not 4-bit. The code uses only 8 bits, so
using, e.g., 0x101 does not lead to a specification exception.

Fix by checking all 16 bits.

  8. hw/s390x/s390-virtio-ccw: Remove superfluous code to set the NIC model 

    The check for nd->model being NULL was originally required, but in
commit e11f463 ("s390x/virtio: use qemu_check_nic_model()")
the corresponding code had been replaced by a call to the function
qemu_check_nic_model() - and this in turn calls qemu_find_nic_model()
which contains the same check for nd->model being NULL again. So we
can remove this from the calling site now.

  9. include/hw/virtio/virtio-gpu: Fix virtio-gpu with blob on big endian … 

    …hosts

Using "-device virtio-gpu,blob=true" currently does not work on big
endian hosts (like s390x). The guest kernel prints an error message
like:

 [drm:virtio_gpu_dequeue_ctrl_func [virtio_gpu]] *ERROR* response 0x1200 (command 0x10c)

and the display stays black. When running QEMU with "-d guest_errors",
it shows an error message like this:

 virtio_gpu_create_mapping_iov: nr_entries is too big (83886080 > 16384)

which indicates that this value has not been properly byte-swapped.
And indeed, the virtio_gpu_create_blob_bswap() function (that should
swap the fields in the related structure) fails to swap some of the
entries. After correctly swapping all missing values here, too, the
virtio-gpu device is now also working with blob=true on s390x hosts.

  11. target/s390x: Fix the "ignored match" case in VSTRS 

    Currently the emulation of VSTRS recognizes partial matches in presence
of \0 in the haystack, which, according to PoP, is not correct:

    If the ZS flag is one and a zero byte was detected
    in the second operand, then there can not be a
    partial match ...

Add a check for this. While at it, fold a number of explicitly handled
special cases into the generic logic.

  13. docs/about/license: Update LICENSE URL 

    In early 2021 (see commit 2ad7843 "docs: update README to use
GitLab repo URLs") almost all of the code base was converted to
point to GitLab instead of git.qemu.org. During 2023, git.qemu.org
switched from a git mirror to a http redirect to GitLab (see [1]).

Update the LICENSE URL to match its previous content, displaying
the file raw content similarly to gitweb 'blob_plain' format ([2]).
