This is\ndone in order to reserve space inside.\nBut rbp has been chosen here only because it is not a scratch register,\nso that the address of the exception stack remains in rbp after calling\ndo_debug(), we can then release the exception stack space without the\nneed to retrieve its address again.\n\nBut we can pick another non-scratch register to do that, so that we\npreserve the link to the interrupted stack frame in the stacktraces.\n\nJust randomly choose r12. Every registers are saved just before and\nrestored just after calling do_debug(). And r12 is not used in the\nmiddle, which makes it a perfect candidate.\n\nExample: perf record -g -a -c 1 -f -e mem:$(tasklist_lock_addr):rw\n\nBefore:\n    44.18%  [k] _raw_read_lock\n            |\n            |\n            ---  |--6.31%-- waitid\n                 |\n                 |--4.26%-- writev\n                 |\n                 |--3.63%-- __select\n                 |\n                 |--3.15%-- __waitpid\n                 |          |\n                 |          |--28.57%-- 0x8b52e00000139f\n                 |          |\n                 |          |--28.57%-- 0x8b52e0000013c6\n                 |          |\n                 |          |--14.29%-- 0x7fde786dc000\n                 |          |\n                 |          |--14.29%-- 0x62696c2f7273752f\n                 |          |\n                 |           --14.29%-- 0x1ea9df800000000\n                 |\n                 |--3.00%-- __poll\n\nAfter:\n\n    43.94%  [k] _raw_read_lock\n            |\n            --- _read_lock\n               |\n               |--60.53%-- send_sigio\n               |          __kill_fasync\n               |          kill_fasync\n               |          evdev_pass_event\n               |          evdev_event\n               |          input_pass_event\n               |          input_handle_event\n               |          input_event\n               |          synaptics_process_byte\n               |          psmouse_handle_byte\n               |          psmouse_interrupt\n               |          serio_interrupt\n               |          i8042_interrupt\n               |          handle_IRQ_event\n               |          handle_edge_irq\n               |          handle_irq\n               |          __irqentry_text_start\n               |          ret_from_intr\n               |          |\n               |          |--30.43%-- __select\n               |          |\n               |          |--17.39%-- 0x454f15\n               |          |\n               |          |--13.04%-- __read\n               |          |\n               |          |--13.04%-- vread_hpet\n               |          |\n               |          |--13.04%-- _xcb_lock_io\n               |          |\n               |           --13.04%-- 0x7f630878ce87\n\nNote: it does not only affect perf events but also other stacktraces in\nx86-64.
