Hi Catalin,

Today's linux-next merge of the arm64 tree got a conflict in:

  arch/arm64/include/asm/cputype.h

between commit:

  9eb8a2cdf65c ("arm64: cputype info for Broadcom Vulcan")

from the arm-soc tree and commit:

  d5370f754875 ("arm64: prefetch: add alternative pattern for CPUs without a prefetcher")

from the arm64 tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
