[patch V3 00/37] mm/highmem: Preemptible variant of kmap_atomic & friends
Following up to the discussion in:
https://lore.kernel.org/r/20200914204209.256266093 at linutronix.de
and the second version of this:
https://lore.kernel.org/r/20201029221806.189523375 at linutronix.de
this series provides a preemptible variant of kmap_atomic & related
interfaces.
This is achieved by:
- Removing the RT dependency from migrate_disable/enable()
- Consolidating all
