McKenneypaulmck@kernel.org2025-01-08T21:37:17+00:00urn:sha1:df0cee43114bd212e3fc9add2a18639605049b95
Most of the this_cpu_*() operations may be used in preemptible code,
but not this_cpu_ptr(), and for good reasons. Therefore, better explain
the reasons and call out raw_cpu_ptr() as an alternative in certain very
special cases.

There are a number of random documents that seem to be
describing some aspects of the core-api. Move them to such
directory, adding them at the core-api/index.rst file.
