SubjectErrors compiling 2.3.51
    I'm new to kernel development, so I apologize if I'm not sending
this patch correctly.

When compiling version 2.3.51 of the kernel with modules disabled, I
got the following error messages from the linker:
fs/fs.o: In function 'fs_name'
fs/fs.o(.text+0x580d): undefined reference to 'try_inc_mod_count'
fs/fs.o: In function 'get_fs_type':
fs/fs.o(.text+0x5949): undefined reference to 'try_inc_mod_count'
fs/fs.o: In function 'mount_root':
fs/fs.o(.init+0x116): undefined reference to 'try_inc_mod_count'
drivers/parport/parport.a(parport_pc.o): In function 'parport_pc_init':
parport_pc.o(.text.init+0x116): undefined reference to
'parport_pc_init_pci'

I changed fs/super.c to eliminate references to try_inc_mod_count
whenever CONFIG_MODULES is undefined. I also eliminated references to
parport_pc_init_pci, since parport_pc_init_pci doesn't seem to be
defined anywhere. I've pasted my patch for super.c below. Since my fix
for parport_pc_init_pci is rather crude, I haven't included a patch for
it here. You can fix it rather simply by commenting out any references
to parport_pc_init_pci. On my computer, I just commented it out in
include/asm/parport.h, though I don't know about other architectures.
