Subject[PATCH 5.17 045/146] RISC-V: KVM: Remove s & u as valid ISA extension
Date
From: Atish Patra <atishp@rivosinc.com>

[ Upstream commit 3ab75a793e4939519d288ef1994db73b8e2d1d86 ]

There are no ISA extension defined as 's' & 'u' in RISC-V specifications.
The misa register defines 's' & 'u' bit as Supervisor/User privilege mode
enabled. But it should not appear in the ISA extension in the device tree.

Remove those from the allowed ISA extension for kvm.

Fixes: a33c72faf2d7 ("RISC-V: KVM: Implement VCPU create, init and
destroy functions")
