[PATCH] Add new TAINT_KSPLICE flag for when a Ksplice update has been loaded.

Distributions and kerneloops.org have requested that the Ksplice
rebootless update system taint the kernel the first time that a
Ksplice update is installed, in order to assist with bug triage.

Ksplice uses a new taint flag, TAINT_KSPLICE, displayed as 'K', for
this purpose.

We would like to confirm that this use of taint meets with the
community's approval and get this taint flag registered in mainline.
