This converts some of the visually simpler cases that have been split
over multiple lines.  I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.

Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script.  I probably had made it a bit _too_ trivial.

So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.

The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

Pull tracing fixes from Steven Rostedt:

 - Fix accounting of stop_count in file release

   On opening the trace file, if "pause-on-trace" option is set, it will
   increment the stop_count. On file release, it checks if stop_count is
   set, and if so it decrements it. Since this code was originally
   written, the stop_count can be incremented by other use cases. This
   makes just checking the stop_count not enough to know if it should be
   decremented.

   Add a new iterator flag called "PAUSE" and have it set if the open
   disables tracing and only decrement the stop_count if that flag is
   set on close.

 - Remove length field in trace_seq_printf() of print_synth_event()

   When printing the synthetic event that has a static length array
   field, the vsprintf() of the trace_seq_printf() triggered a
   "(efault)" in the output. That's because the print_fmt replaced the
   "%.*s" with "%s" causing the arguments to be off.

 - Fix a bunch of typos

Pull probes updates from Masami Hiramatsu:
 "Stack usage reduction for probe events:
   - Allocate string buffers from the heap for uprobe, eprobe, kprobe,
     and fprobe events to avoid stack overflow
   - Allocate traceprobe_parse_context from the heap to prevent
     potential stack overflow
   - Fix a typo in the above commit

  New features for eprobe and tprobe events:
   - Add support for arrays in eprobes
   - Support multiple tprobes on the same tracepoint

  Improve efficiency:
   - Register fprobe-events only when it is enabled to reduce overhead
   - Register tracepoints for tprobe events only when enabled to resolve
     a lock dependency

  Code Cleanup:
   - Add kerneldoc for traceprobe_parse_event_name() and
     __get_insn_slot()
   - Sort #include alphabetically in the probes code
   - Remove the unused 'mod' field from the tprobe-event
   - Clean up the entry-arg storing code in probe-events

  Selftest update
   - Enable fprobe events before checking enable_functions in selftests"

Sort the #include directives in trace_probe* files alphabetically for
easier maintenance and avoid double includes.
This also groups headers as linux-generic, asm-generic, and local
headers.
