Thanks, this patch fixes it. With the patch applied, I see

Zone ranges:
  DMA      [mem 0x0000000000000000-0x00000fffffffdfff]
  Normal   empty
Movable zone start for each node
Early memory node ranges
  node   0: [mem 0x0000000000000000-0x00000001ffffffff]
  node   0: [mem 0x0000000400000000-0x00000005ffffffff]
Initmem setup node 0 [mem 0x0000000000000000-0x00000005ffffffff]

If you want to send me this patch with your S-o-b I'll take it through
my alpha git tree.

The patch is on its way :)

Thanks a bunch, Mike, for the patch and for all you do!

Now I'm really curios how commit e7793e53901b ("arc: update comment about
HIGHMEM implementation") will work out.

Oh, sure, I've copied the wrong line from the log :)
 

You probably mean fdb7d9b7acd0 ("alpha: remove DISCONTIGMEM and
NUMA"). Works well so far!

Maybe in some alternative universe where I have infinite free time
(and my own power plant!) I'll get a second AlphaServer ES47 with the
enormous "hose" [1] to link the two and I'll poke you for guidance on
restoring NUMA support :)

Heh, I'm not sure that restoring NUMA on alpha is really good use for free
time even if it were infinite :)
