Subject: [PATCH v3 0/1] RISC-V KVM ONE_REG interface for SBI

This series first does few cleanups/fixes (PATCH1 to PATCH5) and adds
ONE-REG interface for customizing the SBI interface visible to the
Guest/VM.

The testing of this series has been done with KVMTOOL changes in
riscv_sbi_imp_v1 branch at:
https://github.com/avpatel/kvmtool.git

These patches can also be found in the riscv_kvm_sbi_imp_v3 branch at:
https://github.com/avpatel/linux.git

Changes since v2:
 - Improve ONE_REG interface to allow enabling/disabling multiple SBI
   extensions in one ioctl().

Changes since v1:
 - Dropped patches 1 to 8 since these are already merged.
 - Rebased on Linux-6.3-rc4
