RE: [microblaze-uclinux] undefined __down_interruptible and __up

[<victor-sv_yeo@xxxxxxxxxxx>]

John,

I tried that. Upon insmod, I still see warning of:

Unknown symbol __up
Unknown symbol __down_interruptible

And so insmod fails.

The strange thing is in /proc/kallsyms, I can see the symbol of:
24xxxxxx T __down_interruptible
24xxxxxx T __up

Is the dynamic linking failing here?

Rgds,
Victor Yeo

Can you please add

EXPORT_SYMBOL(__down_interruptible);
EXPORT_SYMBOL(__up);

to linux-2.6.x/arch/microblaze/kernel/semaphore.c

and report if it solves the problem?

Thanks,

John
