KS2010: Security

I posted three small constification patches to kernel-janitors and Cc LKML yesterday - but for users' protection, the authors of the patches getting in are much less important than the fact the patches _really_ get in :)
As noted by Brad above, and in my mails, non-const instances of constifiable structs have been added post-2.6.35, although these structs were already checked for by checkpatch.pl... not good.

Getting the constification patches in will reduce the number of files touched by the grsecurity patch: it's not unusual for the constification to be the only set of changes affecting a given file.
