Hi, Willy

This is the v3 generic part1 for rv32, all of the found issues of v2
part1 [1] have been fixed up, several generic patches have been fixed up
and merged from v2 part2 [2] to this series, the standalone test_fork
patch [4] is merged with a Reviewed-by line into this series too.

This series is based on 20230528-nolibc-rv32+stkp5 branch of [5].

Changes from v2 -> v3:

* selftests/nolibc: fix up compile warning with glibc on x86_64

  Use simpler 'long long' conversion instead of old #ifdef ...
  (Suggestion from Willy)

* tools/nolibc: add missing nanoseconds support for __NR_statx

  Split the compound assignment into two single assignments
  (Suggestion from Thomas)

* selftests/nolibc: add new gettimeofday test cases

  Removed the gettimeofday(NULL, &tz)
  (Suggestion from Thomas)

All of the commit messages have been re-checked, some missing
Suggested-by lines are added.

The whole patchset have been tested on arm, aarch64, rv32 and rv64, no
regressions (the next compile patchset is required to do rv32 test).

The nolibc-test has been tested with glibc on x86_64 too.

Btw, we have found such poll failures on arm (not introduced by this
patchset), this will be fixed in our coming ppoll_time64 patchset:

48 poll_null = -1 ENOSYS                                        [FAIL]
49 poll_stdout = -1 ENOSYS                                      [FAIL]
50 poll_fault = -1 ENOSYS  != (-1 EFAULT)                       [FAIL]

And the gettimeofday_null removal patch from Thomas [3] may conflicts
with the gettimeofday removal and addition patches, but it is not hard
to fix.

Best regards,
Zhangjin
