Subject: selftests/mm: skip virtual_address_range tests on riscv
Date: Tue, 8 Oct 2024 17:41:41 +0800
RISC-V doesn't currently have the behavior of restricting the virtual
address space which virtual_address_range tests check, this will
cause the tests fail. So lets disable the whole test suite for riscv64
for now, not build it and run_vmtests.sh will skip it if it is not present.
