      "message": "x86,kgdb: Fix DEBUG_RODATA limitation using text_poke()\n\nThere has long been a limitation using software breakpoints with a\nkernel compiled with CONFIG_DEBUG_RODATA going back to 2.6.26. For\nthis particular patch, it will apply cleanly and has been tested all\nthe way back to 2.6.36.\n\nThe kprobes code uses the text_poke() function which accommodates\nwriting a breakpoint into a read-only page.  The x86 kgdb code can\nsolve the problem similarly by overriding the default breakpoint\nset/remove routines and using text_poke() directly.\n\nThe x86 kgdb code will first attempt to use the traditional\nprobe_kernel_write(), and next try using a the text_poke() function.\nThe break point install method is tracked such that the correct break\npoint removal routine will get called later on.\n\nCc: x86@kernel.org\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: H.
