Subject: [PATCH 2/3] KVM: selftests: riscv: Fix alignment of the guest_hang() function
Date: Tue, 29 Mar 2022 12:59:10 +0530 [thread overview]
Message-ID: <20220329072911.1692766-3-apatel@ventanamicro.com> (raw)
In-Reply-To: <20220329072911.1692766-1-apatel@ventanamicro.com>
The guest_hang() function is used as the default exception handler
for various KVM selftests applications by setting it's address in
the vstvec CSR. The vstvec CSR requires exception handler base address
to be at least 4-byte aligned so this patch fixes alignment of the
guest_hang() function.
Fixes: 3e06cdf10520 ("KVM: selftests: Add initial support for RISC-V
64-bit")
