As the Archlinux kernel does not support kmemleak:

[8:04] brief:android-apk% zgrep -i meml /proc/config.gz                
CONFIG_INPUT_FF_MEMLESS=m
# CONFIG_DEBUG_KMEMLEAK is not set

I'll give the latest kernel tree from Linus a try this evening and if it
is in there. If not, I'll go back to 3.5.4 in Linus tree and try again.

Cheers,

Nico
