kmemleak: Pull request

[Catalin Marinas]

Linus,

Please consider pulling the kmemleak patches from the branch detailed
below.

These patches have been posted/reviewed on several occasions on LKML and
available in the linux-next tree for about two kernel release cycles.
The necessary x86-specific patch is merged via the x86 tree and the
ARM-specific one via RMK's tree (these only add some vmlinux.lds.S
symbols).

Thanks.

Ok, I got conflicts with the slab/earlyboot changes, but they looked 
resolvable. I haven't tested the merge though, so please do give it a good 
check.

I tested it with both slab and slub allocators and seems alright (and
found a possible leak in tty_ldisc.c). I'll give it a try with slob as
well.

There are two more trivial patches to merge. I'll send them as replies
to this mail but you can pull them directly from the same for-linus
branch:

[PATCH 1/2] kmemleak: Remove the kmemleak.h include in drivers/char/vt.c

This file is no longer annotated for false positives but the kmemleak.h
include was still present.

[PATCH 2/2] kmemleak: Add more info to the MAINTAINERS entry

[Catalin Marinas]

The patch adds the "F:" fields to the KMEMLEAK MAINTAINERS entry and
also moves it before KMEMTRACE to preserve the alphabetical order.
