Hi all:
I knew the kernel implement the per-cpu variable via __percpu_seg. For example on x86 architecture, it's defined as:
#ifdef CONFIG_X86_64
#define __percpu_seg gs
#define __percpu_mov_op movq
#else
#define __percpu_seg fs
#define __percpu_mov_op movl
#endif
But I'm curious where __percpu_seg is initialized?? I fail to find the relative code. Thanks.
