Can't call function provided by kernel

Can't call function provided by kernel

[Hsu I-Chieh]

Hi all,

I'm writing a kernel module in kernel 2.6.x. I called local_flush_tlb_all() 
in my module 
and there is no error or warning during compiling time. The code fragment 
is as follow:

#include <asm/tlbflush.h>

void tlb_flush()
{
    ....
    local_flush_tlb_all();
    ....
}

But when i insert this module into kernel, the message below is displayed:
    mymodule: Unknown symbol local_flush_tlb_all
    insmod: cannot insert `./mymodule.ko': Success (2): Success

Please do help!!

TIA
 
With regards,

Jacky Hsu

perhaps you mean __flush_tlb_all() ?

The problem is probably that local_flush_tlb_all() is not exported. It
appears to only be exported on IA64.

In fact, it appears the entire function does not exist on all that many
architectures!
