arm64: Reject modules with internal alternative callbacks
[ Upstream commit 8e8ae788964aa2573b4335026db4068540fa6a86 ]
During module loading, check if a callback function used by the
alternatives specified in the '.altinstruction' ELF section (if present)
is located in core kernel .text. If not fail module loading before
callback is called.
