USB webcam driver

[Leena Vachhani]

I am trying to compile USB webcam driver (which works fine with RH 9.0 linux
2.4.20-8 kernel) with montavista linux for IBM PPC405 architecture. The header
file asm/current.h is giving error as "Invalid register name for 'current'".
Header file current.h has only one statement :

register struct task_struct *current asm ("r2");

I don't have any clue what is the problem in this statement. Please help me out.

Thanks
