This asserts on the user-mode tcg tests:

https://gitlab.com/qemu-project/qemu/-/jobs/8388145379
https://gitlab.com/qemu-project/qemu/-/jobs/8388145391

TEST catch-syscalls-with-libinline.so on aarch64
**
ERROR:../target/arm/tcg/sve_helper.c:6321:sve_stN_r: code should not be reached
timeout: the monitored command dumped core
Aborted
make[1]: *** [Makefile:185:
run-plugin-catch-syscalls-with-libinline.so] Error 134

Does this need "target/arm: Drop user-only special case in sve_stN_r"
now? (I'd picked that up into target-arm.next but feel free to slot it
in here if something in this series depends on it.)

thanks

Yes it does.  I should have double-checked that was merged, not just queued.

I'll re-spin with that sorted before "Fix user-only probe_access_internal plugin check", 
which is of course what exposes the target/arm issue.
