Hi Nathan,

/usr/include/{bits,sys}/mman.h does not have a definition for 
MADV_NORMAL. Instead, it is defined in /usr/include/asm/mman.h:

#define MADV_NORMAL     0x0             /* default page-in behavior */
#define MADV_RANDOM     0x1             /* page-in minimum required */
#define MADV_SEQUENTIAL 0x2             /* read-ahead aggressively */
#define MADV_WILLNEED   0x3             /* pre-fault pages */
#define MADV_DONTNEED   0x4             /* discard these pages */
