[Linux-ia64] hp_simserial_driver required for real kernel

[Will Cohen <wcohen@redhat.com>]

I am starting with the linux-2.5.69.tar.bz2 and 
linux-2.5.69-ia64-030521.diff.bz2 to generate kernel sources. It appears 
there is a problem with this version of the code. I am building akernel 
for a real ia64 machine with the following options turned off:

CONFIG_IA64_GENERIC=y
# CONFIG_IA64_HP_SIM is not set

# HP Simulator drivers
#
# CONFIG_HP_SIMETH is not set
# CONFIG_HP_SIMSERIAL is not set
# CONFIG_HP_SIMSCSI is not set

The "make compressed" fails with the following error message:

Certainly when building for a real machine there should be no need for 
the simulator serial port. Is there a fix for this? Has anyone 
successfully built the  2.5.69 kernel with the patch for a real machine?
