Subject: [PATCH 1/2] 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.
