Subject: [PATCH 2.6.19-rc1] ehca firmware interface based on Anton Blanchard's new hvcall interface
Hello Roland!
Below is the patch of ehca according to Anton's new hvcall interface, which has been
committed in Paul's git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git
Besides the changes above this patch contains some coding style updates.
I created this patch against your git tree, branch for-2.6.19.
Thanks!
