Hi,<br>
<br>
I am not able to understand the DEFINE macro used in<br>
arch/powerpc/kernel/asm-offsets.c<br>
<br>
I suppose the DEFINE is present in<br>
include/linux/kbuild.h<br>
where it says<br>
#define DEFINE(sym, val) \<br>
asm volatile("\n->" #sym " %0 " #val : : "i" (val))<br>
<br>
What does the above mean?<br>
<br>
<br>
