There was a mistake in the attribute file name. The following is
correct.

* For Intel MSR
/.../index0/prefetcher/hwpf/disable
/.../index0/prefetcher/ippf/disable
/.../index2/prefetcher/hwpf/disable
/.../index2/prefetcher/aclpf/disable

* For A64FX
/.../index[0,2]/prefetcher/hwpf/disable
/.../index[0,2]/prefetcher/hwpf/dist
/.../index[0,2]/prefetcher/hwpf/strong
