[Linux-ia64] hp_simserial_driver required for real kernel

[Will Cohen]

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:


         ld  -static -T arch/ia64/vmlinux.lds.s arch/ia64/kernel/head.o 
arch/ia64/kernel/init_task.o   init/built-in.o --start-group

undefined reference to `hp_simserial_driver'

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?

Will,

Yes, there is a bad dependency between hpsim_console.c and the simserial code.
I ran into it last week but did not get a chance to fix it just yet.
