[PATCH 0/2] Support for set_memory_* outside of module space

[Laura Abbott]

Hi,

Based on a recent discussion[1] there is interest in having set_memory_* work
on kernel memory for security and other use cases. This patch adds the
ability for that to happen behind a kernel option. If this is welcome enough,
the Kconfig can be dropped. This has been briefly tested but not stress tested.

Thanks,
Laura
