Many arm builds still fail as attached. Is it really only me seeing this problem ?

FWIW, if we need/want to use unified assembler in v4.9.y, shouldn't all unified
assembler patches be applied ?

$ git log --oneline v4.9..c001899a5d6 arch/arm | grep unified
c001899a5d6c ARM: 8843/1: use unified assembler in headers
a216376add73 ARM: 8841/1: use unified assembler in macros
eb7ff9023e4f ARM: 8829/1: spinlock: use unified assembler language syntax
32fdb046ac43 ARM: 8828/1: uaccess: use unified assembler language syntax
1293c2b5d790 ARM: dts: berlin2q: add "cache-unified" to l2 node
75fea300d73a ARM: 8723/2: always assume the "unified" syntax for assembly code

I am quite concerned especially about missing commit 75fea300d73a,
which removes the ARM_ASM_UNIFIED configuration option. That means it is
still present in v4.9.y, but the failing builds don't enable it. Given that,
the build failures don't seem to be surprising.
