The patch titled
apply type enum zone_type fix

This patch was dropped because it was folded into apply-type-enum-zone_type.patch
------------------------------------------------------
Subject: apply type enum zone_type fix
From: Paul Jackson <pj@xxxxxxx>
The variable 'k' was changed from 'int' to 'enum zone_type' (unsigned), and
it was being tested for being '>= 0' in a loop. Result was that the
set_mempolicy(MPOL_BIND) system call crashed the kernel in a near infinite
loop off into the weeds.
