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
