Since kernel 4.9, the thread_info has been moved into task_struct, no
longer locates at the bottom of kernel stack.
See commits c65eacbe290b ("sched/core: Allow putting thread_info into
task_struct") and 15f4eae70d36 ("x86: Move thread_info into
task_struct").
Before fix:
(gdb) set $current = $lx_current()
(gdb) p $lx_thread_info($current)
$1 = {flags = 1470918301}
(gdb) p $current.thread_info
$2 = {flags = 2147483648}
After fix:
(gdb) p $lx_thread_info($current)
$1 = {flags = 2147483648}
(gdb) p $current.thread_info
$2 = {flags = 2147483648}
