Consolidate preadv/preadv64 implementation
This patch consolidates all the preadv{64} implementation for Linux in only one (sysdeps/unix/sysv/linux/preadv{64}.c). It also removes the syscall from the auto-generation using assembly macros. It was based on previous pread/pread64 consolidation patch. The new macro SYSCALL_LL{64} is used to handle the offset argument and alias is created for __ASSUME_OFF_DIFF_OFF64 in case of pread64. Checked on x86_64, i386, aarch64, and powerpc64le. * misc/Makefile (CFLAGS-preadv.c): New variable: add cancellation required flags. (CFLAGS-preadv64.c): Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/preadv.c: Remove file. * sysdeps/unix/sysv/linux/generic/wordsize-32/preadv64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/preadv64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/preadv.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/preadv64.: Likwise. * sysdeps/unix/sysv/linux/x86_64/x32/syscalls.list (preadv): Remove syscall from auto-generation. * sysdeps/unix/sysv/linux/preadv.c: Rewrite implementation. [WORDSIZE == 64] (preadv64): Remove macro. [!PREADV] (PREADV): Likewise. [!PREADV] (PREADV_REPLACEMENT): Likewise. [!PREADV] (PREAD): Likewise. [!PREADV] (OFF_T): Likewise. [!__ASSUME_PREADV] (PREADV_REPLACEMENT): Likewise. (LO_HI_LONG): Remove macro. [__WORDSIZE != 64 || __ASSUME_OFF_DIFF_OFF64] (preadv): Add function. * sysdeps/unix/sysv/linux/preadv64.c: Rewrite implementation. (PREADV): Remove macro. (PREADV_REPLACEMENTE): Likewise. (PREAD): Likewise. (OFF_T): Likewise. (preadv64): New function. * nptl/tst-cancel4.c (tf_preadv): Add test.
