  "message": "powerpc: Fix checkstop in native_hpte_clear() with lockdep\n\nnative_hpte_clear() is called in real mode from two places:\n- Early in boot during htab initialisation if firmware assisted dump is\n  active.\n- Late in the kexec path.\n\nIn both contexts there is no need to disable interrupts are they are\nalready disabled. Furthermore, locking around the tlbie() is only required\nfor pre POWER5 hardware.\n\nOn POWER5 or newer hardware concurrent tlbie()s work as expected and on pre\nPOWER5 hardware concurrent tlbie()s could result in deadlock. This code\nwould only be executed at crashdump time, during which all bets are off,\nconcurrent tlbie()s are unlikely and taking locks is unsafe therefore the\nbest course of action is to simply do nothing. Concurrent tlbie()s are not\npossible in the first case as secondary CPUs have not come up yet.\n\nSigned-off-by: Cyril Bur \u003ccyrilbur@gmail.com\u003e\nSigned-off-by: Michael Ellerman \u003cmpe@ellerman.id.au\u003e\n",
