This series adds optional feature lists to struct definitions in the
QAPI schema and makes use of them to advertise the new behaviour of
auto-read-only=on in file-posix.
v2:
- Check that features have well-formed names instead of just checking
that they are strings
- Use QAPISchemaFeature
Sometimes, the behaviour of QEMU changes compatibly, but without a
change in the QMP syntax (usually by allowing values or operations that
previously resulted in an error). QMP clients may still need to know
whether the extension is available.

KVM now supports reporting supported Hyper-V features through CPUID

net_client_init() uses a variable length array to store the prefix

This patch introduces g_strsplit() to split the 'ipv6-net' parameter,

ADD *. At least for one variant we have a gvec helper we can reuse.

Fairly easy to implement, we can make use of the existing CC helpers
cmps64 and cmpu64 - we siply have to sign extend the elements.

A galois field multiplication in field 2 is like binary multiplication,
however instead of doing ordinary binary additions, xor's are performed.
So no carries are considered.
Implement all variants via helpers. s390_vec_sar() and s390_vec_shr()
will be reused later on.

Take care of properly taking the modulo of the count. We might later
want to come back and create a variant of VERLL where the base register
is 0, resulting in an immediate.

Again, part of vector enhancement facility 1. The operation corresponds

We can use all the fancy new vector helpers implemented by Richard.
One important thing to take care of is always to properly mask of

Let's return the cc value directly via cpu_env. Unfortunately there
isn't a simple way to calculate the value lazily - one would have to
calculate and store e.g. the population count of the mask and the
result so it can be evaluated in a cc helper.
But as VTM only sets the cc, we can assume the
Fairly easy as only 128-bit handling is required. Simply perform the
subtraction and then subtract the borrow.
