2022-07-25selftests/powerpc/ptrace: Convert to load/store doublesMichael Ellerman
Some of the ptrace tests check the contents of floating pointer registers. Currently these use float, which is always 4 bytes, but the ptrace API supports saving/restoring 8 bytes per register, so switch to using doubles to exercise the code more fully.
