As discussed on LSF/MM, kill kmemcheck.

KASan is a replacement that is able to work without the limitation of
kmemcheck (single CPU, slow). KASan is already upstream.

We are also not aware of any users of kmemcheck (or users who don't consider
KASan as a suitable replacement).

From Documentation/kasan.txt:

    therefore you will need a certain version of GCC > 4.9.2

AFAIK gcc 4.9.3 hasn't been released yet. (Or does it mean >= 4.9.2 ?)

Can we perhaps wait until there is a released version of GCC that supports
KASan? And maybe then a touch longer so folks can test it works on their
platforms?
