The state of Classic Rate Monotonic is currently protected by the Giant lock and ISR disable sections. Use a per-object ISR lock to protect state changes instead.

Resolution: fixed
Status: newclosed

In 90960bd11a91259d9aace3870692dbe2e227de0f/rtems:

rtems: Rework rate-monotonic scheduler

Use the default thread lock to protect rate-monotonic state changes.
This avoids use of the Giant lock. Split rtems_rate_monotonic_period()
body into several static functions. Introduce a new thread wait class
THREAD_WAIT_CLASS_PERIOD for period objects to synchronize the blocking

Close #2631.
