From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Avnish Chouhan Date: Mon, 27 Mar 2023 12:25:39 +0530 Subject: [PATCH] kern/ieee1275/init: Convert plain numbers to constants in Vec5 This patch converts the plain numbers used in Vec5 properties to constants. 1. LPAR: Client program supports logical partitioning and associated hcall()s. 2. SPLPAR: Client program supports the Shared Processor LPAR Option. 3. CMO: Enables the Cooperative Memory Over-commitment Option. 4. MAX_CPU: Defines maximum number of CPUs supported.
