Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux 

Pull arm64 fixes from Catalin Marinas:

 - Fix occasional page fault during boot due to memblock resizing before
   the linear map is up.

 - Define NET_IP_ALIGN to 0 to improve the DMA performance on some
   platforms.

 - lib/raid6 test build fix.

 - .mailmap update for Punit Agrawal
