Description Adhemerval Zanella 2021-10-18 20:00:53 UTC 
On riscv32 there are two regressions:

  FAIL: misc/tst-ntp_gettime
  FAIL: misc/tst-ntp_gettimex

On Linux side, the clock_adjtime syscall (kernel/time/posix-timers.c:1112) which maps to __NR_clock_gettime64 on 32-bit with legacy 32-bit and __NR_clock_gettime otherwise always use __kernel_timex.

Since 32-bit systems with TIMESIZE=64 __USE_TIME_BITS64 is not defined, on suc systems the wrong kernel interface is used.

Fixed on 2.35.
