Florian Rommel ec0b6d17a5 scripts/gdb: fix failing KGDB detection during probe ... 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.
