  "message": "powerpc/book3e-64: Fix debug support for userspace\n\nWith the introduction of CONFIG_PPC_ADV_DEBUG_REGS user space debug is\nbroken on Book-E 64-bit parts that support delayed debug events.  When\nswitch_booke_debug_regs() sets DBCR0 we\u0027ll start getting debug events as\nMSR_DE is also set and we aren\u0027t able to handle debug events from kernel\nspace.\n\nWe can remove the hack that always enables MSR_DE and loads up DBCR0 and\njust utilize switch_booke_debug_regs() to get user space debug working\nagain.\n\nWe still need to handle critical/debug exception stacks \u0026 proper\nsave/restore of state for those exception levles to support debug events\nfrom kernel space like we have on 32-bit.\n\nSigned-off-by: Kumar Gala \u003cgalak@kernel.crashing.org\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n",
