From: Michael Kowal <kowal@linux.vnet.ibm.com>

Making some pre-requisite alignment changes ahead of the following patch
sets.  Making these changes now will ease the review of the patch sets.

Checkpatch wants the closing comment '*/' on a separate line, unless it is
on the same line as the starting comment '/*'.

There are also changes to prevent lines from spanning 80 columns.

Changed block of defines from:
   #define A 1  /* original define comment is not
                 * preferred, but not flagged... */
   #define B 2  /* Newly added define comment
                 * is flagged with a warning */
To:
   #define A 1  /* original define comment is */
                /* now fine, no warning...    */
   #define B 2  /* Newly added define comment */
                /* is fine...                 */
