Subject: [PATCH 0/4] scripts/gdb: Fixes for $lx_current and $lx_per_cpu

Hi all,

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.

Regards,
Flo
