Hi,
Hi,

I am trying to call udelay from my kernel module.
And I am getting this undefined symbol error.

I checked up the relavant code
in linux/include/asm-arm/delay.h

#define udelay(n)                                               \
        (__builtin_constant_p(n) ?                              \
          ((n) > (MAX_UDELAY_MS * 1000) ? __bad_udelay() :      \
                        __const_udelay((n) * 0x68dbul)) :       \
          __udelay(n))

Now, where are these __const_udelay and __bad_udelay defined ??

__const_udelay seem to be in arch/.../lib/delay.c while I couldn't
find any place where __bad_udelay() is defined. Can anyone help us
out?

Jinesh.
