upend_idx != done_idx we still set zcopy_used to true and rollback this choice
later. This could be avoided by determining zerocopy once by checking all

CLASS-dev.c is a common idiom for Linux subsystems
This pulls all the code related to the miscdev into tpm-dev.c and makes it
static. The identical file_operation structs in the drivers are purged and the
tpm common code unconditionally creates the miscdev.

For some reason this driver thinks that chip->data_buffer needs
to be set before it can call tpm_pm_*. This is not true. data_buffer
is used only by /dev/tpmX, which is why it is managed exclusively
by the fops functions.

TPM drivers should not call dev_set_drvdata (or aliases), only the core

Some thought is needed to determine what locality in-kernel users
should be using. I suspect userspace and kernel space should not be
forced to the same locality.
Should user space be restricted to a subset of localities?
What use models do you see with the security label binding mec
The hope is to have a well defined locality API that all the other
locality aware drivers can use, perhaps in 3.13.

Some other arches page protect the kernel, but that tends to be at
odds with the desire to use huge pages for the kernel mapping, and
