Where is __get_user_bad?

Mad_C · 06-23-2003, 07:49 AM

Since I changed some copy_from_user statements to get_user, my character device driver won't load because of "unresolved symbol __get_user_bad". I am using ARM-Linux 2.4.18-rmk7 on an SSV DNP1110 (SA1110 StrongARM).
What am I missing?

Hmm. In include/asm-arm/uaccess.h is a line "extern int __get_user_bad(void);",
while in arch/arm/lib/getuser.S there is a note saying " * Note also that it is intended that __get_user_bad is not global."
So, htf is that intended to work?

Pleez, somebody enlighten me!

when you compile this module, -O is needed

Better late than never...
Took me a while to remember what this was all about, but I apparently got it fixed one way or the other.

Thanks anyway for the reply,
