[PATCHv3 00/16] set_memory_* functions header refactor

[PATCHv3 00/16] set_memory_* functions header refactor

[Laura Abbott]

Hi,

This is v3 of the series to decouple set_memory_* from cacheflush.h. This
version contains a few minor alphabetical order fixes and some fixes caught
by the 0day bot. Several places unfortunately need an #ifdef around the
header for arches without the set_memory_* functions.

Andrew, it might be best to wait a few days to let the 0day bot churn on this
series.

Thanks,
Laura

[PATCHv3 01/16] treewide: Move set_memory_* functions away from cacheflush.h

[Laura Abbott]

The set_memory_* APIs came out of a desire to have a better way to
change memory attributes. Many of these attributes were linked to cache
functionality so the prototypes were put in cacheflush.h. These days,
the APIs have grown and have a much wider use than just cache APIs. To
support this growth, split off set_memory_* and friends into a separate
header file to avoid growing cacheflush.h for APIs that have nothing to
do with caches.
