The newer version of the emulator contains several bug fixes, one that
we were seeing in our use of vtpm.
This patch also defines TPM_STRONG_PERSISTENCE for the new emulator.
A couple of important notes about this patch:
-This has only been tested on PVM domU's. In theory it should work for
HVM but I have not tried it at all and can guarantee nothing.
-All the relevant changes in tools/vtpm/vtpm.patch have been ported
to tpm_emulator-0.5.1.
-None of the changes in tpm_emulator.patch have been ported. In
particular this means the BUILD_EMULATOR option, which as I understand
lets you use the tpm_emulator in dom0 for a machine that does
not have a real hardware TPM does not work. This functionality should
be easy to add though because the new emulator already comes with a
kernel module interface.
-No considerations were made for the VTPM_MULTI_VM feature (which is
supposedly unfinished). This patch may or may not break any progress
made on that feature.

This has finally bugged me enough to do something about it:
make prints `***' when it stops due to an error. With make -j, and/or
with automated build systems, this error marker can be in the middle
of a large logfile. It is useful to be able to search for it.
Therefore change occurrences of `*' to `=' for information and warning
messages. `***' is reserved for cases where the build stops.
A corresponding change is being applied to qemu-xen-unstable.

* Move .PHONY directives next to targets,
this makes them a lot harder to miss
* Add missing .PHONY directives
* Remove nonexistent .PHONY directives
* Hopefully I didn'T miss anything...

gmp dev files are installed. If files are missing, Makefile exits with a
message indicating that these tools will not be built, rather than an
error, which prevents Xen from building.

The VTPM manager and VTPMs fully support both 32 and 64 bit OSes. The
tpm_emulator (provided for debugging on TPM-less machines) does not
support 64-bit kernels by default though. See the README for details on
how to use it on 64-bit kernels.
