4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: James Morse <james.morse@xxxxxxx> commit 8fac5cbdfe0f01254d9d265c6aa1a95f94f58595 upstream. The hyp-stub is loaded by the kernel's early startup code at EL2 during boot, before KVM takes ownership later. The hyp-stub's text is part of the regular kernel text, meaning it can be kprobed. A breakpoint in the hyp-stub causes the CPU to spin in el2_sync_invalid. Add it to the __hyp_text.
