This patch corrects the order of the calls to register_chrdev() and
pcmcia_register_driver().  Now udev correctly creates userspace device
files /dev/cmmN and /dev/cmxN respectively.

Based on an earlier patch by Jan Niehusmann <jan@gondor.com>.

1ac3836ce6 [PATCH] tipar oops fix
If compiled into the kernel, parport_register_driver() is called before the
parport driver has been initalised.

This means that it is expected that tp_count is 0 after the
parport_register_driver() call() - tipar's attach function will not be
called until later during bootup.

9e18ee1917 [PATCH] tpm: command duration update
With the TPM 1.2 Specification, each command is classified as short, medium or
long and the chip tells you the maximum amount of time for a response to each
class of command.  This patch provides and array of the classifications and a
function to determine how long the response should be waited for.  Also, it
uses that information in the command processing to determine how long to poll
for.  The function is exported so the 1.2 driver can use the functionality to
determine how long to wait for a DataAvailable interrupt if interrupts are
being used.

3c2f606a09 [PATCH] tpm: spacing cleanups
The following patch set contains numerous changes to the base tpm driver
(tpm.c) to support the next generation of TPM chips.  The changes include new
sysfs files because of more relevant data being available, a function to
access the timeout and duration values for the chip, and changes to make use
of those duration values.  Duration in the TPM specification is defined as the
maximum amount of time the chip could take to return the results.  Commands
are in one of three categories short, medium and long.  Also included are
cleanups of how the commands for the sysfs files are composed to reduce a
bunch of redundant arrays.

This patch:

Fix minor spacing issues.

permissions to 0220 (owner and group can write).

The use case for this driver is to configure the fail over behavior of the
clock hardware.  That should be done by the more privileged users.

9453a5adaf [PATCH] ptmx: fix duplicate idr_remove
Remove duplicate call to idr_remove() in ptmx_open.

Error during open can result in call to release_dev() followed by call to
idr_remove().  release_dev already calls idr_remove so the second call can
cause a stack dump in idr_remove()->sub_remove() flagging an attempt to
release an already released entry.

I reproduces this on a machine with a misconfigured X server (attempting to
restart multiple times rapidly) getting the same error as the 1st link
below.

This also seems to be related to:

http://marc.theaimsgroup.com/?l=selinux&m=110596994916785&w=2

The stack dump can occur on close (as well as open) as shown
in the 1st instance above, possible from something like:

process A - open (index=0), open fail to out1,
  release_dev calls idr_remove (index 0), down(sem) sleeps
process B - open (index=0), open OK (idr allocated)
process A - wake and call idr_remove on index 0
...
process B - close, release_dev, stack dump on idr_remove (index=0)
  because entry already removed

e1a2509023 [PATCH] make tty_insert_flip_string_flags() a non gpl export
We changed the wrong symbol.  It's tty_insert_flip_string_flags() which is
called from the previously-non-GPL'ed now-inlined tty_insert_flip_char().

Fix that up, and uninline tty_schedule_flip() while we're there.
