-/* Default implementation will use __NR_fadvise64 with expected argument
- positions (for instance i386 and powerpc32 that uses __ALIGNMENT_ARG).
-
- Second option will be used by arm which define __NR_arm_fadvise64_64
- (redefined to __NR_fadvise64_64 in kernel-features.h) that behaves as
- __NR_fadvise64_64 (without the aligment argument required for the ABI).
-
- Third option will be used by both tile 32-bits and mips o32. Tile
- will set __ASSUME_FADVISE64_64_NO_ALIGN to issue a 6 argument syscall,
- while mips will use a 7 argument one with __NR_fadvise64.
-
- s390 implements fadvice64_64 using a specific struct with arguments
- packed inside. This is the only implementation handled in arch-specific
- code. */
