Hi all,

After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

mm/vmstat.c:614: warning: "MAX_THRESHOLD" redefined
  614 | #define MAX_THRESHOLD 0
      | 
mm/vmstat.c:172: note: this is the location of the previous definition
  172 | #define MAX_THRESHOLD 125
      | 
mm/vmstat.c:614: warning: "MAX_THRESHOLD" redefined
  614 | #define MAX_THRESHOLD 0
      | 
mm/vmstat.c:172: note: this is the location of the previous definition
  172 | #define MAX_THRESHOLD 125
      | 

Introduced by commit

  5f6bac149e10 ("mm: vmstat: fix /proc/sys/vm/stat_refresh generating false warnings")

The preproccesor directives look like this:

#ifdef CONFIG_SMP
#define MAX_THRESHOLD 125
#ifdef CONFIG_HAVE_CMPXCHG_LOCAL
#else
#define MAX_THRESHOLD 0

So I guess the second MAX_THRESHOLD was put after the wrong #else?
