[ANNOUNCE] v5.2.21-rt15

Dear RT folks!

I'm pleased to announce the v5.2.21-rt15 patch set.

Changes since v5.2.21-rt14:

  - Since the migrate_disable() rework, the kernel did not build on UP
    or without RT enabled. Patch by Daniel Wagner.

  - Since the migrate_disable() rework, with heave changing of the
    task's affinity mask the kernel could issue a warning in
    migrate_enable() and crash later.

Known issues
     - None
