 >       kmemcheck: enable in the x86 Kconfig

This patch does:

 > +config KMEMCHECK
 > +	bool "kmemcheck: trap use of uninitialized memory"
 > +	depends on X86_32

So it's only possible to select kmemcheck on 32-bit builds, But you also
seem to have 64-bit stuff, eg

 >       kmemcheck: support for 64-bit
 >       kmemcheck: add missing pte_hidden() for x86-64

so is the Kconfig patch slightly out-of-date?
