In order to save 128 bytes from the vsyscall_0 zone, we move __vgetcpu_mode & __jiffies to vsyscall_2 zone where they really belong, since they are used only from vgetcpu() (which is in this vsyscall_2 area). After patch is applied, new layout is : ffffffffff600000 T vgettimeofday ffffffffff60004e t vsysc2 ffffffffff600140 t vread_hpet ffffffffff600150 t vread_tsc ffffffffff600180 D __vsyscall_gtod_data ffffffffff600400 T vtime ffffffffff600413 t vsysc1 ffffffffff600800 T vgetcpu ffffffffff600870 D __vgetcpu_mode ffffffffff600880 D __jiffies ffffffffff600c00 T venosys_1 Signed-off-by: Eric Dumazet Signed-off-by: Andi Kleen Cc: Andi Kleen Signed-off-by: Andrew Morton --- Reading git-diff-tree failed
