[PATCHv3 0/2] arm64 CONFIG_DEBUG_SET_MODULE_RONX support

[Laura Abbott]

Hi,

This adds support for CONFIG_DEBUG_SET_MODULE_RONX for arm64. The last version
was added as part of a series to add RWX permissions for the rest of memory[1].
That series still needs quite a bit of work though so I'm submitting this
separately.

Thanks,
Laura
