powerpc: Replace lxvd2x/stxvd2x with lvx/stvx in P7's memcpy/memmove
POWER9 DD2.1 and earlier has an issue where some cache inhibited vector load traps to the kernel, causing a performance degradation. To handle this in memcpy and memmove, lvx/stvx is used for aligned addresses instead of lxvd2x/stxvd2x. Reference: https://patchwork.ozlabs.org/patch/814059/ * sysdeps/powerpc/powerpc64/power7/memcpy.S: Replace lxvd2x/stxvd2x with lvx/stvx. * sysdeps/powerpc/powerpc64/power7/memmove.S: Likewise.
