You reported this as a -tip build failure - but it appears to be some sort of kbuild
bug/artifact, right? There was a leftover .memmove_64.o.cmd file from an old tree.

When jumping between kernel versions via git checkout a 'make mrproper' is generally
needed. In most cases 'make' will figure things out but it's not always guaranteed.

So for example there are version transitions where a stale include/asm links could
cause build problems.
