Blank line between these

Done.

 namespace base {

  public:

-
   // Returns true iff this is a low-end device.
   static bool IsLowEndDevice();

+  // Return the device's RAM size in kilo-bytes. Used for testing.
   static size_t AmountOfPhysicalMemoryKB();

It seems like these should be merged with base/sys_info.h which has this kind of
thing in it.

[c.shu, 2014/06/10 17:36:26]

Right, this function simply returns SysInfo::AmountOfPhysicalMemory() / 1024.
Maybe we can even remove it.

 
  private:
   SysUtils();
-
-  static bool IsLowEndDeviceFromJni();
-  static size_t AmountOfPhysicalMemoryKBFromJni();
 };
