Adhemerval Zanella Netto - Aug. 19, 2016, 2:41 p.m.
This patch consolidates all the posix_fallocate{64} implementation for Linux
in only one (sysdeps/unix/sysv/linux/posix_fallocate{64}.c).  It also removes
the syscall from the auto-generation using assembly macros.

The macro SYSCALL_LL{64} is used to handle the offset argument along with
the new INTERNAL_SYSCALL_CALL macro to define correct argument count for
internal INTERNAL_SYSCALL call.

Tested on x86_64, i686, x32, aarch64, ppc64le, and armhf.

        * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fallocate.c: Remove
        file.
        * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fallocate64.c:
        Likewise.
        * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fallocate.c: Likewise.
        * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fallocate64.c:
        Likewise.
        * sysdeps/unix/sysv/linux/wordsize-64/posix_fallocate.c: Likewise.
        * sysdeps/unix/sysv/linux/wordsize-64/posix_fallocate64.c: Likewise.
        * sysdeps/unix/sysv/linux/posix_fallocate.c (posix_fallocate): Use
        SYSCALL_LL to pass both offset and len arguments.
        * sysdeps/unix/sysv/linux/posix_fallocate64.c (posix_fallocate64):
        Likewise.
