2021-08-26softmmu: Use accel_find("xen") instead of xen_available()Peter Maydell
The xen_available() function is used only to produce an error for some Xen-specific command line options in QEMU binaries where Xen support was not compiled in: it just returns the value of the CONFIG_XEN define. Now that accelerators are QOM classes, we can check for "does this binary have Xen compiled in" with accel_find("xen"), and drop the xen_available() function.

2021-08-26target/arm/cpu64: Validate sve vector lengths are supportedAndrew Jones
Future CPU types may specify which vector lengths are supported. We can apply nearly the same logic to validate those lengths as we do for KVM's supported vector lengths. We merge the code where we can, but unfortunately can't completely merge it because KVM requires all vector lengths, power-of-two or not, smaller than the maximum enabled length to also be enabled. The architecture only requires all the power-of-two lengths, though, so TCG will only enforce that.

2021-08-26target/arm/cpu: Introduce sve_vq_supported bitmapAndrew Jones
Allow CPUs that support SVE to specify which SVE vector lengths they support by setting them in this bitmap. Currently only the 'max' and 'host' CPU types supports SVE and 'host' requires KVM which obtains its supported bitmap from the host. So, we only need to initialize the bitmap for 'max' with TCG. And, since 'max' should support all SVE vector lengths we simply fill the bitmap. Future CPU types may have less trivial maps though.

2021-08-26qapi: Fix crash on redefinition with a different conditionMarkus Armbruster
QAPISchema._make_implicit_object_type() asserts that when an implicit object type is used multiple times, @ifcond is the same for all uses. It will be for legitimate uses, i.e. simple union branch wrapper types. A comment explains this. The assertion fails when a command or event is redefined with a different condition. The redefinition is an error, but it's flagged only later. Fixing the assertion would complicate matters further. Not worthwhile, drop it instead. We really need to get rid of simple unions. Tweak test case redefined-event to cover redefinition with a different condition.

2021-08-25target/mips: Simplify gen_helper() macros by using tcg_constant_i32()Philippe Mathieu-Daudé
In all call sites the last argument is always used as a read-only value, so we can replace tcg_const_i32() temporary by tcg_constant_i32().
