[patch 10/28] posix-cpu-timers: Remove the stub nanosleep functions

[Thomas Gleixner]

CLOCK_THREAD_CPUTIME_ID implements stub functions for nanosleep and
nanosleep_restart, which return -EINVAL. That return value is
wrong. The correct return value is -ENOTSUP.

Remove the stubs and let the new dispatch code return the correct
error code.
