Add the internal helper get_thread_info that calculated the thread_info
from a given task variable. Also export this service as a convenience
function.
Note: ia64 version is untested.

The internal helper for_each_task iterates over all tasks of the target,
calling the provided function on each. For performance reasons, we cache
a reference to the gdb type object of a task.

Parse the target endianness from the output of "show endian" and cache
the result to return it via the new helper get_target_endiannes. We will
need it for reading integers from buffers that contain target memory.

Provide an internal helper with container_of semantics. As type lookups
are very slow in gdb-python and we need a type "long" for this, cache
the reference to this type object. Then export the helper also as a
convenience function form use at the gdb command line.

This is probably the most useful helper when debugging kernel modules:
lx-symbols will first reload vmlinux. Then it searches recursively for
*.ko files in the specified paths and the current directory. Finally it
walks the kernel's module list, issuing the necessary add-symbol-file
command for eac
This helper probes the type of the gdb server. Supported are QEMU and
KGDB so far. Knowledge about the gdb server is required e.g. to retrieve
the current CPU or current task.

This function allows to obtain a per-cpu variable, either of the current
or an explicitly specified CPU.
Note: sparc64 version is untested.

This pokes into the log buffer of the debugged kernel, dumping it to the
gdb console. Helping in case the target should or can no longer execute
dmesg itself.

Add helpers for reading integers from target memory buffers. Required
when caching the memory access is more efficient than reading individual
values via gdb.

This provides the basic infrastructure to load kernel-specific python
helper scripts when debugging the kernel in gdb.
The loading mechanism is based on gdb loading for -gdb.py when
opening . Therefore, this places a corresponding link to the
main helper script into the output directory that conta
