With WERROR=y, which is default, clang is not happy:

.../amd/pasid.c:168:3: error: call to undeclared function 'mmu_notifier_unregister'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
.../amd/pasid.c:191:8: error: call to undeclared function 'mmu_notifier_register'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
2 errors generated.

Select missed dependency.
