[PATCH] i386: Allow to use GENERICARCH for UP kernels
There are some machines around (large xSeries or Unisys ES7000) that need physical IO-APIC destination mode to access all of their IO devices. This currently doesn't work in UP kernels as used in distribution installers. This patch allows to compile even UP kernels as GENERICARCH which allows to use physical or clustered APIC mode.
