PATCH 1/1 perf, tools: Fix display of data source snoop indication

From: Andi Kleen <[email protected]>

perf mem report doesn't display the data source snoop indication correctly.

In the kernel API the definition is

but the table used by the perf tools exchanged Hit and Miss

        "None",
        "Miss",
        "Hit",

Fix the table in perf.

perf mem: Fix display of data source snoop indication

'perf mem report' doesn't display the data source snoop indication correctly.

In the kernel API the definition is:

  #define PERF_MEM_SNOOP_NONE     0x02 /* no snoop */
  #define PERF_MEM_SNOOP_HIT      0x04 /* snoop hit */
  #define PERF_MEM_SNOOP_MISS     0x08 /* snoop miss */

but the table used by the perf tools exchanged "Hit" and "Miss":

        "None",
        "Miss",
        "Hit",

Fix the table in perf.
