From 66ef20c7834b7df18168b12a57ef01c6ae0d1a81 Mon Sep 17 00:00:00 2001 From: Christophe Lombard Date: Fri, 7 Apr 2017 16:11:54 +0200 Subject: cxl: Remove unused values in bare-metal environment. The two previously fields pid and tid, located in the structure cxl_irq_info, are only used in the guest environment. To avoid confusion, it's not necessary to fill the fields in the bare-metal environment. Pid_tid is now renamed to 'reserved' to avoid undefined behavior on bare-metal. The PSL Process and Thread Identification Register (CXL_PSL_PID_TID_An) is only used when attaching a dedicated process for PSL8 only. This register goes away in CAIA2.
