This broke the selftests build on old toolchains (that don't assume Power4), because we build the kernel source files into the selftests using different ASFLAGS. The fix is simply to add -mpower4 to the selftest ASFLAGS as well. Fixes: 15a3204d24a3 ("powerpc/64s: Set assembler machine type to POWER4") Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

There's also been some conflicting changes in the CPU features code which are best merged and tested before going upstream.
