From cd5dead9d32423d63c802328c0563d7ff29647cd Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Thu, 16 Jul 2015 22:40:27 +0200 Subject: [PATCH] s390/cio: simplify css_generate_pgid Simplify the css_generate_pgid code by using stap() independent of CONFIG_SMP. For !CONFIG_SMP builds stap() will deliver the address of the cpu we IPL'ed from (which can be != 0). Note: the ifdef was likely added to be compatible with _very_ old machines which we don't support anyway.
