This patch consolidate Linux readahead implementation on generic
sysdeps/unix/sysv/linux/readahead.c one. The changes are:
- Assume __NR_readahead existence with current minimum kernel of 3.2
for all architectures.
- Use INLINE_SYSCALL_CALL, __ALIGNMENT_ARG, and SYSCALL_LL64 to pass
the 64 bit offset. This allows architectures with different abis
to use the same implementation.
- Remove arch-specific readahead implementations.
Checked on x86_64-linux-gnu and i686-linux-gnu.
* sysdeps/unix/sysv/linux/arm/readahead.c: Remove file.
* sysdeps/unix/sysv/linux/mips/mips32/readahead.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/n32/syscalls.list (readahead):
Remove.
* sysdeps/unix/sysv/linux/mips/mips64/n64/syscalls.list: Likewise.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/syscalls.list: Likewise.
* sysdeps/unix/sysv/linux/wordsize-64/syscalls.list: Likewise.
* sysdeps/unix/sysv/linux/readahead.c (__readahead): Assume
__NR_readahead existence, and use INLINE_SYSCALL_CALL, __ALIGNMENT_ARG,
and SYSCALL_LL64.
