-stable review patch. If anyone has any objections, please let us know.
------------------
From: Jan-Bernd Themann <[email protected]>
based on 2c69448bbcedebeb8409ddb05fbc7d3fe1cfbda7 in mainline.
The current eHEA module compiled for 64K page kernels can not
be loaded with insmod due to bad hypervisor call parameters.
The patch is a subset of the follwing patch which has been applied
for 2.6.24 upstream:
