Michael Ellerman 5b48ba2fbd powerpc/64s: Fix stf mitigation patching w/strict RWX & hash ... The stf entry barrier fallback is unsafe to execute in a semi-patched state, which can happen when enabling/disabling the mitigation with strict kernel RWX enabled and using the hash MMU. See the previous commit for more details. Fix it by changing the order in which we patch the instructions. Note the stf barrier fallback is only used on Power6 or earlier.
