Re: [PATCH 1/2] c/r: [x86_32] sys_restore to use ptregs prototype

["Serge E. Hallyn" <serue-r/Jw6+rmf7HQT0dZR+AlfA@public.gmane.org>]

Here I guess is the s390 version.  If we need the pt_regs later, we
can get it using get_pt_regs(current) as the clone wrapper right
above it does.

Subject: [PATCH 1/1] define s390x sys_restart wrapper
