Add a new function get_task_cmdline_kernel() which reads the command
line of a process into a kernel buffer. This command line can then be
dumped by arch code to give additional debug info via the parameters
with which a faulting process was started.
The new function re-uses the existing code whic
This patch series dumps the command line (including the program parameters) of
a faulting process to the syslog.
The motivation for this patch is that it's sometimes quite hard to find out and
annoying to not know which program *exactly* faulted when looking at the syslog.
For example, a dump on
Add the function dump_stack_print_cmdline() which can be used by arch
code to print the command line of the current processs. This function
is useful in arch code when dumping information for a faulting process.
Wire this function up in the dump_stack_print_info() function to include
the dumping
The process program name and command line is now shown in generic code
in dump_stack_print_info(), so drop the arc-specific implementation.

If a process segfaults, include the command line of the faulting process
in the syslog.
In the example below, the "crash" program (which simply writes zero to address
0)
was called with the parameters "this is a test":
crash[2326]: segfault at 0 ip 561a7969c12e sp 7ffe97a05630 error 6 i
