[ts-7000] Interrupt generation at user level(In user application)

["manmohan_thakur119" <>]

Dear all,
I am using TS-7250,kernel version-2.4.26.
I am facing a problem regarding ISR handling through DIDO port for 
user level application.

For ISR registering we are using request_irq() for irq no. 59
(GPIOINTR) but it is giving no. of errors and undefined reference 
during compilation through cross compiler (crosstool-cygwin-gcc-
3.3.4-glibc-2.3.2.tar.bz2) after inclusion of kernel level header 
files.
#include <linux/unistd.h>
#include <linux/ioport.h>
#include <linux/interrupt.h>
#include <linux/sched.h>
#include <asm/system.h>
#include <asm/io.h>
#include <asm/irq.h>

Errors are-

$ ./arm-unknown-linux-gnu-gcc -o newSerial newSerial.c
/cygdrive/c/DOCUME~1/DEEPAK~1/LOCALS~1/Temp/ccYV2K7a.o(.text+0x188):

In function
 `sioEnable':
: undefined reference to `restore_flags'
collect2: ld returned 1 exit status

Can anybody provide a right soution for this?
whether we can use request_irq()routine at user level or not,if not 
then what are the other solution for interrupt handling at user 
level application.
