get_thread_info ($lx_thread_info) only accepted a dereferenced task
parameter. Passing a pointer to a task_struct (like $lx_per_cpu does with
KGDB) threw an exception.
With this patch, both (dereferenced values and pointers) are accepted.
Before (on x86, KGDB):
>>> p $lx_per_cpu(cpu_info)
Traceback (most recent call last):
File "./scripts/gdb/linux/cpus.py", line 158, in invoke

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
