Subject: [PATCH 0/3] scripts/gdb: Improve s390 support

Patch 1 adds $lx_current([CPU]) support for s390 to obtain the task of
the active context or a specific CPU.

Patch 2 adds a $lx_lowcore([CPU]) convenience function on s390 to obtain
the s390 lowcore of the active context of a specific CPU.  It is based
on functionality introduced by patch 1.

Patch 3 adds a $lx_cpu() convenience function to obtain the CPU number
of the active context.

Regards,
Jens
