  "message": "powerpc: Fix program check handling when lockdep is enabled\n\nIn commit 54321242afe (\"Disable interrupts early in Program Check\"), we\nswitched from enabling to disabling interrupts in program_check_common.\n\nWhereas ENABLE_INTS leaves r3 untouched, if lockdep is enabled DISABLE_INTS\ncalls into lockdep code and will clobber r3. That means we pass a bogus\nstruct pt_regs* into program_check_exception() and all hell breaks loose.\n\nSo load our regs pointer into r3 after we call DISABLE_INTS.\n\nSigned-off-by: Michael Ellerman \u003cmichael@ellerman.id.au\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n",
