Unresolved symbols in 2.5.47

Hi,

when trying to compile kernel 2.5.47 for my system, I included the hisax driver as a module (hisax.o). At the end of building the kernel, I found a lot of unresolved symbols making it impossible to use hisax as module. I already contacted Karsten Keil and Kai Germaschweski (the ISDN maintainers) about at least one failing symbol and it's also been reported to this list in November before. But since I didn't found any fix for them during a quick look at the kernel source at linux.bkbits.net, I'll post the list of unresolved symbols here:

[salem:/usr/src]-16> nm /lib/modules/2.5.47/kernel/drivers/isdn/hisax/hisax.o|grep " U"

         U __check_region
         U __const_udelay
         U __kfree_skb
         U __release_region
         U __request_region
         U __this_module
         U __wake_up
         U _ctype
         U add_timer
         U alloc_skb
         U copy_to_user
         U cpu_raise_softirq
         U del_timer
         U free_irq
         U get_random_bytes
         U interruptible_sleep_on
         U ioport_resource
         U isapnp_present
         U jiffies
         U kfree
         U kmalloc
         U kstat__per_cpu
         U pci_bus_read_config_byte
         U pci_devices
         U pci_enable_device
         U pci_find_device
         U preempt_schedule
         U printk
         U register_isdn
         U request_irq
         U schedule_timeout
         U schedule_work
         U skb_clone
         U skb_over_panic
         U skb_under_panic
         U softnet_data
         U sprintf
         U try_inc_mod_count
         U vsprintf

I would appreciate if someone would be able to fix this, so that it's possible to use kernel 2.5.47 (or maybe newer kernels) on systems depending on ISDN for their internet connection.

Thanks
Christian
