#     Merge tag 'asm-generic-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
#     
#     Pull asm-generic fix from Arnd Bergmann:
#      "Multiple people reported a bug I introduced in asm-generic/unistd.h in
#       4.20, this is the obvious bugfix to get glibc and others to correctly
#       build again on new architectures that no longer provide the old
#       fstatat64() family of system calls"
#     
#     * tag 'asm-generic-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic:
#       asm-generic: unistd.h: fixup broken macro include.
