I have created shared tag kvm-riscv-shared-tag-6.7 in the
KVM RISC-V repo at:
https://github.com/kvm-riscv/linux.git

This shared tag is based on 6.6-rc5 and contains following 4 patches:
dt-bindings: riscv: Add Zicond extension entry
RISC-V: Detect Zicond from ISA string
dt-bindings: riscv: Add smstateen entry
RISC-V: Detect Smstateen extension

Thanks,
Anup
