[ Upstream commit ebdef0de2dbc40e697adaa6b3408130f7a7b8351 ]
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.
