This made it slightly farther into the kernel module build, it's now 
giving errors about pioctl32:

/home/mwaltz/git/openafs/src/libafs/MODLOAD-3.13.0-34-generic-MP/afs_syscall.c: 
In function 'copyin_afs_ioctl':

  #error pioctl32 not done for this linux
   ^

   ^
make[6]: *** 
[/home/mwaltz/git/openafs/src/libafs/MODLOAD-3.13.0-34-generic-MP/afs_syscall.o] 
Error 1

Which in src/afs/afs_syscall.c looks like it there are blocks for other 
64-bit Linux archs when AFS_LINUX_64BIT_KERNEL is defined. I don't think 
I can just copy the amd64 block for arm64 however since it appears to 
have Intel specifics.

Looking at where AFS_FLOCK is defined as a preprocessor macro in
src/afs/afs.h, it looks like you may be getting the 'flock64' define
instead of 'flock', since AFS_LINUX_64BIT_KERNEL is not defined in your
param.arm64_linux26.h.  I would try adding that (and maybe seeing if there
are similar things missing, by comparing the amd64, i386, and arm versions
of those config headers), and attempting again to build.
