7240b98320 TPM: Wait for TPM_ACCESS tpmRegValidSts to go high at startup
The TIS specification (pg 47) says the valid bit must be set, but
the TPM will not set it until it has completed its internal startup.

The driver checks that the valid bit is set during request_locality,
but it issues a TPM_ACCESS_REQUEST_USE without validating the
valid bit is set.

Some TPMs will ignore the TPM_ACCESS_REQUEST_USE, until valid is
set which causes the request_locality to timeout, which breaks the
driver attach.

Wait one timeout unit for valid to assert. If valid does not assert
then assume -ENODEV.

Seen on embedded with a:
1.2 TPM (device-id 0x3204, rev-id 64)

1f86605729 tpm: Fix cancellation of TPM commands (polling mode)
On one of my machines the cancellation of TPM commands does not work.
The reason is that by writing into sysfs 'cancel' the tpm_tis_ready
call causes the status flag TPM_STS_VALID to be set in the statusregister.
However, the TIS driver seems to wait for TPM_STS_COMMAND_READY.
Once a 2nd time sysfs 'cancel' is written to, the TPM_STS_COMMAND_READY flag
also gets set, resulting in TPM_STS_VALID|TPM_STS_COMMAND_READY to be
read from the status register.

This patch now converts req_canceled into a function to enable more complex
comparisons against possible cancellation status codes.

4643826a3d TPM: Work around buggy TPMs that block during continue self test
We've been testing an alternative TPM for our embedded products and
found random kernel boot failures due to time outs after the continue
self test command.

This was happening randomly, and has been *very* hard to track down, but
it
looks like with this chip there is some kind of race with the
tpm_tis_status()
check of TPM_STS_COMMAND_READY. If things get there 'too fast' then
it sees the chip is ready, or tpm_tis_ready() works. Otherwise it takes
somewhere over 400ms before the chip will return TPM_STS_COMMAND_READY.

Adding some delay after tpm_continue_selftest() makes things reliably
hit the failure path, otherwise it is a crapshot.

The spec says it should be returning TPM_WARN_DOING_SELFTEST, not
holding
off on ready..

Boot log during this event looks like this:

tpm_tis 70030000.tpm_tis: 1.2 TPM (device-id 0x3204, rev-id 64)
tpm_tis 70030000.tpm_tis: Issuing TPM_STARTUP
tpm_tis 70030000.tpm_tis: tpm_transmit: tpm_send: error -62
tpm_tis 70030000.tpm_tis: [Hardware Error]: TPM command timed out during
continue self test
tpm_tis 70030000.tpm_tis: tpm_transmit: tpm_send: error -62
tpm_tis 70030000.tpm_tis: [Hardware Error]: TPM command timed out during

tpm_tis 70030000.tpm_tis: [Hardware Error]: TPM command timed out during
continue self test

The other TPM vendor we use doesn't show this wonky behaviour:
tpm_tis 70030000.tpm_tis: 1.2 TPM (device-id 0xFE, rev-id 70)

1fbc5e9535 tpm_i2c_stm_st33: fix oops when i2c client is unavailable
When no i2c bus exists, user-space can cause an oops by triggering a
device probe through a message sent to an i2c "new_device" sysfs entry.
Adding a check for a NULL i2c client structure in the probe function
closes the hole.

This patch also fixes accessing the NULL client struct in the print
function call reporting the error.

07b133e606 char/tpm: simplify duration calculation and eliminate smatch warning.
This patch changes the semantics of the duration calculation for an
ordinal, by masking out the higher bits of a tpm command, which specify
whether it's an TPM_PROTECTED_COMMAND, TPM_UNPROTECTED_COMMAND,
TPM_CONNECTION_COMMAND, TPM_CONNECTION_COMMAND, TPM_VENDOR_COMMAND.
(See TPM Main Spec Part 2 Section 17 for details).

For all TPM_PROTECTED and TPM_CONNECTION commands the results are
unchanged.
The TPM_UNPROTECTED commands are TSS commands and thus irrelevant as
they are not sent to the tpm.
For vendor commands the semantics change for ordinals 10 and 11 but
they were probably wrong anyway.

For everything else which has the ordinal set to 10 or 11 the semantics
change as it now uses TPM_UNDEFINED instead of TPM_SHORT which was
probably wrong anyway (but irrelevant as not defined by the standard).

This patch also gets rid of the (false positive) smatch warning:

 There's a slightly non-trivial merge in virtio-net, as we cleaned up the

1b6370463e virtio_console: Add support for remoteproc serial
Add a simple serial connection driver called
VIRTIO_ID_RPROC_SERIAL (11) for communicating with a
remote processor in an asymmetric multi-processing
configuration.

This implementation reuses the existing virtio_console
implementation, and adds support for DMA allocation
of data buffers and disables use of tty console and
the virtio control queue.

276a3e954c virtio_console: Merge struct buffer_token into struct port_buffer
Refactoring the splice functionality by unifying the approach for
sending scatter-lists and regular buffers. This simplifies
buffer handling and reduces code size. Splice will now allocate
a port_buffer and send_buf() and free_buf() can always be used
for any buffer.

Here is the "big" char/misc driver patches for 3.8-rc1.  I'm starting to
 put random driver subsystems that I had previously sent you through the
 driver-core tree in this tree, as it makes more sense to do so.
 
 Nothing major here, the various __dev* removals, some mei driver
 updates, and other random driver-specific things from the different
 maintainers and developers.
 
 Note, some MFD drivers got added through this tree, and they are also
 coming in through the "real" MFD tree as well, due to some major
 mis-communication between me and the different developers.  If you have
 any merge conflicts, take the ones from the MFD tree, not these ones,
 sorry about that.

Pull Char/Misc driver merge from Greg Kroah-Hartman:
 "Here is the "big" char/misc driver patches for 3.8-rc1.  I'm starting
  to put random driver subsystems that I had previously sent you through
  the driver-core tree in this tree, as it makes more sense to do so.

  Nothing major here, the various __dev* removals, some mei driver
  updates, and other random driver-specific things from the different
  maintainers and developers.

  Note, some MFD drivers got added through this tree, and they are also
  coming in through the "real" MFD tree as well, due to some major
  mis-communication between me and the different developers.  If you
  have any merge conflicts, take the ones from the MFD tree, not these
  ones, sorry about that.

  All of this has been in linux-next for a while.

Fix up trivial conflict in drivers/mmc/host/Kconfig due to new drivers
having been added (both at the end, as usual..)

cff2f741b8 Driver core updates for 3.8-rc1
Here's the large driver core updates for 3.8-rc1.
 
 The biggest thing here is the various __dev* marking removals.  This is
 going to be a pain for the merge with different subsystem trees, I know,
 but all of the patches included here have been ACKed by their various
 subsystem maintainers, as they wanted them to go through here.
 
 If this is too much of a pain, I can pull all of them out of this tree
 and just send you one with the other fixes/updates and then, after
 3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
 it's up to you.  The merges should all be trivial, and Stephen has been
 doing them all in linux-next for a few weeks now quite easily.
 
 Other than the __dev* marking removals, there's nothing major here, some
 firmware loading updates and other minor things in the driver core.
 
 All of these have (much to Stephen's annoyance), been in linux-next for
 a while.

d3594ea2b3 Merge branch 'block-dev'
Merge 'block-dev' branch.

I was going to just mark everything here for stable and leave it to the
3.8 merge window, but having decided on doing another -rc, I migth as
well merge it now.

This removes the bd_block_size_semaphore semaphore that was added in
this release to fix a race condition between block size changes and
block IO, and replaces it with atomicity guaratees in fs/buffer.c
instead, along with simplifying fs/block-dev.c.

This removes more lines than it adds, makes the code generally simpler,
and avoids the latency/rt issues that the block size semaphore
introduced for mount.

I'm not happy with the timing, but it wouldn't be much better doing this
during the merge window and then having some delayed back-port of it
into stable.

* block-dev:
  blkdev_max_block: make private to fs/buffer.c
  direct-io: don't read inode->i_blkbits multiple times
  blockdev: remove bd_block_size_semaphore again
  fs/buffer.c: make block-size be per-page and protected by the page lock

1e8b33328a blockdev: remove bd_block_size_semaphore again
This reverts the block-device direct access code to the previous
unlocked code, now that fs/buffer.c no longer needs external locking.

With this, fs/block_dev.c is back to the original version, apart from a
whitespace cleanup that I didn't want to revert.
