My feeling is this hunk and the following one should be submitted as
separate patches.

I think the original formatting is more readable; I would align the two
'to's vertically even. You can fix the comment to adhere to the Linux
coding standard though and the whitespace "problem" will vanish
automagically.

yep, this should be:

/*
* ICW2: 8259A-1 IR0-7 mapped to:
*
* - 0x20-0x27 on 32-bit
* - 0x30-0x37 on 64-bit
*/
