1. Factor out general swap_entries_put_map() helper to drop entries belonging to one cluster. If entries are last map, free entries in batch, otherwise put entries with cluster lock acquired and released only once. 2. Iterate and call swap_entries_put_map() for each cluster in swap_entries_put_nr() to leverage batch-remove for last map belonging to one cluster and reduce lock acquire/release in fallback case. 3. As swap_entries_put_nr() won't handle SWAP_HSA_CACHE drop, rename it to swap_entries_put_map_nr(). 4. As we won't drop each entry invidually with swap_entry_put() now, do reclaim in free_swap_and_cache_nr() because swap_entries_put_map_nr() is general routine to drop reference and the relcaim work should only be done in free_swap_and_cache_nr(). Remove stale comment accordingly.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
