[Linux-ia64] Exporting symbol in linux2.4/ia64

[Linux-ia64] Exporting symbol in linux2.4/ia64

[G\351raud Krawezik]

While working on a driver, I've experienced the following when trying to
insmod it (i'm using 2.4-test6):

unresolved symbol clear_page
unresolved symbol softirq_state
unresolved symbol __ia64_memcpy_toio
unresolved symbol __free_pages_ok

softirq_state is a 'case to study', but for the three others, it's
slightly different, as:

clear_page exists in the kernel (nm vmlinux...) but is probably not
exported
__free_pages_ok is present as well, but should be available through a
'classic' function (no __)
__ia64_memcpy_toio does not exist in vmlinux, neither memcpy_toio...
ld problem?

As on 2.2/ia32 I had no problem with clear_page, free_page_ok and
memcpy_toio, I guess that it's just an exporting problem. Now I'm
including directly the object into my driver to debug it, but could you
tell me if in the final release those symbols will remain unexported or
not? (ie: is it just a bug?)


Thanks...

softirq_state was moved and renamed in 2.4.0-test6.  See
include/linux/irq_cpustat.h for the new definitions.  You either
compiled your module against old headers or you are trying to insmod an
old module.  2.4.0-test6 also cleaned up the /lib/modules directory
structure but the transition might have left old structure around, try
"rm -rf /lib/modules/2.4.0-test6" and "make modules_install" to get rid
of any old structure.  Also check that you have modutils 2.3.14.
