[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-changelog] Converge the TPM drivers in the Xen repository
# HG changeset patch
# User cl349@xxxxxxxxxxxxxxxxxxxx
# Node ID 514f2585d102f592b7adef6b8d684003f28dd6d2
# Parent cc63196c0d2ff4d124b5896f6c79ac1392e973d0
Converge the TPM drivers in the Xen repository
with those coming from the 2.6.15 kernel. Some files can now be
taken from 2.6.15 directly and can therefore be removed.
