[PATCH v2 0/3] Documentation: Add real-time bits.

[Sebastian Andrzej Siewior]

I tried to put some real-time related documentation.   
Patch #1 SPDX tag to seqlock.
Patch #2 extends locktypes with local_lock_nested_bh
Patch #3 adds some real-time bits.

In case there is something missing or unclear, please let me know.

v1…v2:
  - #1 does not add a reference tag anymore.
  - #2 wording/ typo in #2
  - #3 is moved to core-api
  - #3 does not uses rst references but uses the plain file name
  - #3 is extended with some notes for architecture porting.

  Documentation: seqlock: Add a SPDX license identifier
  Documentation: locking: Add local_lock_nested_bh() to locktypes
  Documentation: Add real-time to core-api
