[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: scripts/gdb: make get_thread_info accept pointers
has been removed from the -mm tree.  Its filename was
     scripts-gdb-make-get_thread_info-accept-pointers.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: scripts/gdb: make get_thread_info accept pointers
Date: Thu, 25 Apr 2024 17:35:00 +0200

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
    return per_cpu(var_ptr, cpu)
           ^^^^^^^^^^^^^^^^^^^^^
  File "./scripts/gdb/linux/cpus.py", line 42, in per_cpu
    cpu = get_current_cpu()

  File "./scripts/gdb/linux/cpus.py", line 33, in get_current_cpu
