Adhemerval Zanella Netto - June 28, 2016, 7:04 p.m.
Change from previous version:

 - Remove __WORDSIZE and __ASSUME_OFF_DIFF_OFF64 usage.

--

This patch consolidates all the fallocate{64} implementation for Linux
in only one (sysdeps/unix/sysv/linux/fallocate{64}.c).  It also removes the
syscall from the auto-generation using assembly macros.

The new macro SYSCALL_LL{64} is used to handle the offset argument.

Checked on x86_64, x32, i386, aarch64, and ppc64le.

	* sysdeps/unix/sysv/linux/fallocate.c (fallocate): Use SYSCALL_LL
	macro on offset argument.
	* sysdeps/unix/sysv/linux/fallocate64.c (fallocate64): Use
	SYSCALL_LL64 on offset argument.
	* sysdeps/unix/sysv/linux/mips/mips64/n32/fallocate.c: Remove file.
	* sysdeps/unix/sysv/linux/mips/mips64/n32/fallocate64.c: Likewise.
	* sysdeps/unix/sysv/linux/mips/mips64/n64/fallocate.c: Likewise.
	* sysdeps/unix/sysv/linux/mips/mips64/n64/fallocate64.c: Likewise.
	* sysdeps/unix/sysv/linux/wordsize-64/fallocate.c: Likewise.
	* sysdeps/unix/sysv/linux/wordsize-64/fallocate64.c: Likewise.
	* sysdeps/unix/sysv/linux/x86_64/x32/syscalls.list (fallocate): Remove
	syscall auto-generation.
	* sysdeps/unix/sysv/linux/Makefile (test): Add tst-fallocate and
	tst-fallocate64.
	* sysdeps/unix/sysv/linux/tst-fallocate.c: New file.
	* sysdeps/unix/sysv/linux/tst-fallocate64.c: Likewise.

This redirection is also needed for posix_fadvise() and
posix_fallocate(). See my recent patch.

Yes, I am aware. *This* patch is only for fallocate{64}, I plan to
unify posix_fadvise and posix_fallocate in another submission.
