  This patchset fixes 2 issues recently found with newer stat tests
(s390-32 missing nanoseconds support on legacy stat calls and
MIPSn64 y2106 limitation), adds the __ASSUME_STATX optimization
on fstatat/fstatat64, and improve the 64 bit timestamp tests on
Linux.

I have checked on i686-linux-gnu and x86_64-linux-gnu
(kernel 5.4 x86_64-64) and on powerpc-linux-gnu and
(kernel 5.10 ppc64).

I also tested the utimensat tests on mips64el on two kernels:
4.1.4 (without statx support) and 5.10 (with statx support).
On 4.1.4 kernel the tst-utime now shows the missing y2106
support:

| $ ./testrun mist/tst-utime
| warning: skipping tests[3] { 100000000, fffffffe }: unsupported timestamp value
| warning: skipping tests[4] { 100000001, 100000002 }: unsupported timestamp value

While on a 5.10 kernel all the tests pass without any warning.

Adhemerval Zanella (5):
  linux: Implement fstatat with __fstatat64_time64
  linux: Disable fstatat64 fallback if __ASSUME_STATX is defined
  linux: Use statx for MIPSn64
  support: Add support_path_support_time64_value
  linux: Add y2106 support on utimensat tests
