| H A D | entry_64_compat.S | diff f3d415ea46968ae1f9cbb9e201601d7207ce74c7 Tue Feb 20 15:01:13 CST 2018 Dominik Brodowski <linux@dominikbrodowski.net> x86/entry/64: Open-code switch_to_thread_stack()
Open-code the two instances which called switch_to_thread_stack(). This
allows us to remove the wrapper around DO_SWITCH_TO_THREAD_STACK.
While at it, update the UNWIND hint to reflect where the IRET frame is,
and update the commentary to reflect what we are actually doing here.
