KVM: selftests: Define literal to asm constraint in aarch64 as unsigned long
Define a literal '0' asm input constraint to aarch64/page_fault_test's guest_cas() as an unsigned long to make clang happy. tools/testing/selftests/kvm/aarch64/page_fault_test.c:120:16: error: value size does not match register size specified by the constraint and modifier [-Werror,-Wasm-operand-widths] :: "r" (0), "r" (TEST_DATA), "r" (guest_test_memory)); ^ tools/testing/selftests/kvm/aarch64/page_fault_test.c:119:15: note: use constraint modifier "w" "casal %0, %1, [%2]\n" ^~ %w0 Fixes: 35c581015712 ("KVM: selftests: aarch64: Add aarch64/page_fault_test") Cc: Ricardo Koller <ricarkol@google.com> Signed-off-by: Sean Christopherson <seanjc@google.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-Id: <20221213001653.3852042-2-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
