* [ia64] Workaround #325070 until upstream works out an acceptable solution. 

This bug breaks module loading on non-SMP ia64 kernels.  The workaround
  is to temporarily use an SMP config for the non-SMP kernels.  (Note that
  John Wright is running benchmarks to determine the overhead of running
  an SMP kernel on UP systems to help decide if this should be a
  permanent change).

# [PATCH] sys_set_mempolicy() doesnt check if mode < 0
#
# A kernel BUG() is triggered by a call to set_mempolicy() with a negative
# first argument. This is because the mode is declared as an int, and the
# validity check doesnt check < 0 values. Alternatively, mode could be
# declared as unsigned int or unsigned long.
