Kernel driver ibmaem
======================
+This driver talks to the IBM Systems Director Active Energy Manager, known
+henceforth as AEM.
+
Supported systems:
- * Any recent IBM System X server with Active Energy Manager support.
+ * Any recent IBM System X server with AEM support.
This includes the x3350, x3550, x3650, x3655, x3755, x3850 M2,
x3950 M2, and certain HS2x/LS2x/QS2x blades. The IPMI host interface
driver ("ipmi-si") needs to be loaded for this driver to do anything.

Description
-----------
-This driver implements sensor reading support for the energy and power
-meters available on various IBM System X hardware through the BMC. All
-sensor banks will be exported as platform devices; this driver can talk
-to both v1 and v2 interfaces. This driver is completely separate from the
-older ibmpex driver.

-The v1 AEM interface has a simple set of features to monitor energy use.
-There is a register that displays an estimate of raw energy consumption
-since the last BMC reset, and a power sensor that returns average power
-use over a configurable interval.

-The v2 AEM interface is a bit more sophisticated, being able to present

Special Features
----------------
-The "power_cap" value displays the current system power cap, as set by
-the Active Energy Manager software. Setting the power cap from the host
