THis patch consolidates all Linux ftruncate implementation on
sysdeps/unix/sysv/linux/ftruncate{64}.c. It is based on
{INTERNAL,INLINE}_SYSCALL patch [1] to simplify the syscall construction.
General idea is to build ftruncate iff __OFF_T_MATCHES_OFF64_T is not
defined, otherwise ftruncate64 will be build and ftruncate will be an
alias. The fallocate will use old compat syscall and pass 32-bit off_t
argument, while fallocate64 will handle the correct off64_t passing using
__ALIGNMENT_ARG and SYSCALL_LL64 macros.
Tested on x86_64, i386, aarch64, and armhf.
* posix/tst-truncate-common.c: New file.
* posix/tst-truncate.c: Use tst-truncate-common.c.
* posix/tst-truncate64.c: Likewise and add LFS tests.
* sysdeps/unix/sysv/linux/arm/ftruncate64.c: Remove file.
* sysdeps/unix/sysv/linux/generic/wordsize-32/ftruncate.c: Likewise.
* sysdeps/unix/sysv/linux/generic/wordsize-32/ftruncate64.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips32/ftruncate64.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/ftruncate64.c: Likewise.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/ftruncate64.c: Likewise.
* sysdeps/unix/sysv/linux/wordsize-64/ftruncate64.c: Likewise.
* sysdeps/unix/sysv/linux/ftruncate.c: New file.
* sysdeps/unix/sysv/linux/ftruncate64.c (__ftruncate64): Use
INLINE_SYSCALL_CALL, __ALIGNMENT_ARG and SYSCALL_LL64 macros.
[__OFF_T_MATCHES_OFF64_T] (ftruncate): Add alias.
* sysdeps/unix/sysv/linux/mips/mips64/syscalls.list (ftruncate):
Remove.
* sysdeps/unix/sysv/linux/wordsize-64/syscalls.list (ftruncate):
Likewise.
