Update.
* sysdeps/unix/sysv/linux/i386/pread64.c: Removed, we can use the normal version now. * sysdeps/unix/sysv/linux/arm/pread64.c: Likewise. * sysdeps/unix/sysv/linux/arm/pwrite64.c: Likewise. * sysdeps/unix/sysv/linux/mips/pread64.c: Likewise. * sysdeps/unix/sysv/linux/mips/pwrite64.c: Likewise. * sysdeps/unix/sysv/linux/pwrite64.c (__libc_pwrite64): Check endianness to check how to pass argument. * sysdeps/unix/sysv/linux/pread64.c (__libc_pread64): Likewise.
