Patch series "scripts/gdb: Fixes for $lx_current and $lx_per_cpu".

This series fixes several bugs in the GDB scripts related to the
$lx_current and $lx_per_cpu functions.  The changes were tested with GDB
10, 11, 12, 13, and 14.

Patch 1 fixes false-negative results when probing for KGDB

Patch 2 fixes the $lx_per_cpu function, which is currently non-functional
in QEMU-GDB and KGDB.

Patch 3 fixes an additional bug in $lx_per_cpu that occurs with KGDB.

Patch 4 fixes the incorrect detection of the current CPU number in KGDB,
which silently breaks $lx_per_cpu and $lx_current.


This patch (of 4):

The KGDB probe function sometimes failed to detect KGDB for SMP machines
as it assumed that task 2 (kthreadd) is running on CPU 0, which is not
necessarily the case.  Now, the detection is agnostic to kthreadd's CPU.
