[PATCH] libc: Remove 32bit timespec structures everywhere.

by Dmitry Chestnykh

With time64 enabled we use statx() system call and the appropriate routines for results conversion. There is no need in `__ts32_struct` anymore.

[PATCH] Fix *stat() and *stat64() when the time is beyond year 2038.

To obtain correct `st_atim`, `st_mtim` and `st_ctim` fields we need to use statx() syscall and then convert the data from the kernel to the regular stat structure.

[PATCH] Add time64 support for PowerPC.

by Dmitry Chestnykh

PowerPC is big-endian architecture, so there are some significant differences in comparison with time64 support for little-endian architectures like ARM and xtensa. The main difference is that we strictly need to pass two 64bit values to system calls because Linux Kernel internally uses `struct __ketnel_timespec` and similar, which consists of two 64bit fields. For this reason many files have been changed to convert timespec-family structures (mixed of 64bit and 32bit values) to the 64bit-only structures for using as system calls args. Now time64 syscalls works properly both for LE (ARM, xtensa) and BE (PPC) memory layouts.

[PATCH] xtensa: Add time64 support.

by Dmitry Chestnykh

- xtensa is the second architecture that supports time64 inside uClibc-ng. - Linux Kernel always uses 32bit time variables inside `stat` structures, so there is a need to use `st_atime`, `st_mtime` and `st_ctime` structures with the same 32bit-wide `tv_sec` and `tv_nsec` variables even if time64 is enabled.
