Subject: [PATCH] KVM: arm64: nv: select XARRAY_MULTI to fix build error
populate_nv_trap_config() uses xa_store_range(), which is only built
when XARRAY_MULTI is set, so select that symbol to prevent the build error.
aarch64-linux-ld: arch/arm64/kvm/emulate-nested.o: in function `populate_nv_trap_config':
emulate-nested.c:(.init.text+0x17c): undefined reference to `xa_store_range'
Fixes: d15fe1b2d2cc ("KVM: arm64: nv: Add trap forwarding infrastructure")
