# HG changeset patch

# Node ID e3ad9b9c95eedaa44144e97c34024ba902dca0bf
# Parent da8da6e1e1d609b1ceedb552475b72684e8461f5
[TPM] Add an upgrade patch to bring TPM subsystem to 2.6.17-rc4.
This patch adds the updated and newer driver plugins appearing in
2.6.17-rc4 to the 2.6.16.13 kernel. The patch needs to be placed into
the patches/linux-2.6.16.13 directory and should be removed once an
upgrade is done to 2.6.17-rc4 or later version.
