[PATCH v5 0/8] set_memory() routines and STRICT_MODULE_RWX

[Russell Currey]

Repost from v4 because I somehow missed half of the final patch.

Picking up from Christophe's last series, including the following changes:

- [6/8] Cast "data" to unsigned long instead of int to fix build
- [8/8] New, to fix an issue reported by Jordan Niethe

Christophe's last series is here:
