i have feeling that your new LMB code will hit 2.6.36. and
x86 patches that is using to lmb will hit 2.6.37.

otherwise it will make more merge conflicts between tip and lmb.
unless put your lmb change to tip?

why are you thinking that there is time bomb in the patches?
I even provide the option to use x86 own low to high allocation.
really don't know where is the time bomb.

my -v14 patches only touch several lines your core lmb code, and have near 0 affect
to original lmb users.
