Many fixes are debatable. Could you please split your patch on smaller
patches, at least per-file basis, but also better on per-change-type
basis.

Additionally, please, do not put so much crap into the subject line.

Thanks!

Use ALIGN()

Can you just kill this whole dbg() stuff - I t is useless nowadays.

All the { } stuff should be in a separate patch.

The patch is too large, no one is going to merge it because it is
difficult to get confident it is doing a good thing. Split it.
