   # HEAD: 16767502aa990cca2cb7d1372b31d328c4c85b40 selftests: kselftest: Fix build failure with NOLIBC

Misc timer fixes:

 - Address a (valid) W=1 build warning

 - Fix timer self-tests

 - Annotate a KCSAN warning wrt. accesses to the
   tick_do_timer_cpu global variable.

 - Address a !CONFIG_BUG build warning

Heads up for the !CONFIG_BUG warning patch, which we
addressed with:

   5284984a4fba bug: Fix no-return-statement warning with !CONFIG_BUG

Not everyone agreed though, see:

Thanks,

	Ingo
