For the purpose of rebuild_hflags_a64, we do not need to compute all of the va parameters, only tbi. Moreover, we can compute them in a form that is more useful to storing in hflags. This eliminates the need for aa64_va_parameter_both, so fold that in to aa64_va_parameter. The remaining calls to aa64_va_parameter are in get_phys_addr_lpae and in pauth_helper.c. This reduces the total cpu consumption of aa64_va_parameter in a kernel boot plus a kvm guest kernel boot from 3% to 0.5%.
