[GIT PULL] Kmemleak fixes

[Catalin Marinas]

Hi Linus,

Could you please pull the kmemleak branch again? One of the changes
fixes a Kconfig select conflict with kmemcheck. The other is a cosmetic
update to the kmemleak messages. Thanks.

Hi Linus,

Would you please consider merging the kmemleak branch?

It contains several fixes to bugs raised recently and also reduces the
number of false positives to nearly 0 (actually making the tool usable -
one of the slub kmalloc calls for large blocks was completely missed and
bootmem allocations would need to be tracked as well since many of them
contain valid pointers).

Thanks.

Hi Linus,

Could you please pull the kmemleak branch? This is hopefully the last
set of kmemleak changes for 2.6.31 (there may be some false positive
annotations). It seems to be consistent on my x86 hardware now but with
a few leak reports which I need to look at.

Thanks.
