__up, __down_trylock & __down_interruptible for MIPS

[<priya.mani@wipro.com>]

Hi 

I need to build a driver on the kernel version 2.4.22 on Mips
architecture ( I am using an AMD board). When I try to insmod the driver
it gives unresolved symbols for "__up, __down_trylock &
__down_interruptible". 

I checked in the semaphore.c file under kernel/arch/mips. The above
symbols are neither defined nor exported while they are done for the
semaphore files under other arch like sparc, sh, alpha etc.

If I try to use the functions from the latest CVS files in the mips-org
site it gives other compilation errors.

Please can you tell me how do I go about this problem. Have the above
functions been obsoleted? Is there any patch available for them? Or is
there any doc explaining this? I am using Kernel version 2.4.22.

Can anybody help me out with this please.

Rgds
