Merge patch series "riscv: add SBI FWFT misaligned exception delegation support"

Clément Léger <cleger@rivosinc.com> says:

The SBI Firmware Feature extension allows the S-mode to request some
specific features (either hardware or software) to be enabled. This
series uses this extension to request misaligned access exception
delegation to S-mode in order to let the kernel handle it. It also adds
support for the KVM FWFT SBI extension based on the misaligned access
handling infrastructure.

FWFT SBI extension is part of the SBI V3.0 specifications [1]. It can be
tested using the qemu provided at [2] which contains the series from
[3]. Upstream kvm-unit-tests can be used inside kvm to tests the correct
delegation of misaligned exceptions. Upstream OpenSBI can be used.

The tests can be run using the kselftest from series [4].
