[RESEND 0/2] coccicheck: Add M= option

[RESEND 0/2] coccicheck: Add M= option

[Gregory.Dietsche]

From: Greg Dietsche <Gregory.Dietsche@cuw.edu>

This is a re-post of the patches found here: https://lkml.org/lkml/2011/6/7/714

Could I get the appropriate aks/naks to get these into the kernel? Also, I've added Michal Marek to the CC list since it is my understanding that he's the one that will eventually commit these. Thanks!!

This patch set adds support for M= to coccicheck. This makes 
using Coccinelle easier for those wishing to check specific
drivers or sub systems with Coccinelle.
