If a virtio-console device gets unplugged while a port is open, a
subsequent close() call on the port accesses vqs to free up buffers.
This can lead to a crash.
The buffers are already freed up as a result of the call to
unplug_ports() from virtcons_remove(). The fix is to simply not access
vq information if port->portdev is NULL.

This reverts commit c4ff4b829ef9e6353c0b133b7adb564a68054979.
Ted Ts'o reports:
"TPM is working for me so I can log into employer's network in 2.6.37.
It broke when I tried 2.6.38-rc6, with the following relevant lines
from my dmesg:
[ 11.081627] tpm_tis 00:0b: 1.2 TPM (device-id 0x0, rev-id 78)
[ 25.734114] tpm_tis 00:0b: Operation Timed out
[ 78.040949] tpm_tis 00:0b: Operation Timed out
This caused me to get suspicious, especially since the _other_ TPM
commit in 2.6.38 had already been reverted, so I tried reverting
commit c4ff4b829e: "TPM: Long default timeout fix". With this commit
reverted, my TPM on my Lenovo T410 is once again working."

This reverts commit 9b29050f8f75916f974a2d231ae5d3cd59792296.

release_region/release_mem_region
Request_region should be used with release_region, not release_resource.
This patch contains a number of changes, related to calls to request_region,
request_mem_region, and the associated error handling code.
1. For the call to request_region, the variable io_resource storing the
result is dropped. The call to release_resource at the end of the function
is changed to a call to release_region with the first two arguments of
request_region as its arguments. The same call to release_region is also
added to release_ipwireless.
2. The first call to request_mem_region is now tested and ret is set to
-EBUSY if the the call has failed. This call was associated with the
initialization of ipw->attr_memory. But the error handling code was
testing ipw->common_memory. The definition of release_ipwireless also
suggests that this call should be associated with ipw->common_memory, not
ipw->attr_memory.
3. The second call to request_mem_region is now tested and ret is
set to -EBUSY if the the call has failed.
4. The various gotos to the error handling code is adjusted so that there
is no need for ifs.
5. Return the value stored in the ret variable rather than -1.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression x,E;
@@
(
*x = request_region(...)
|
*x = request_mem_region(...)

The current TPM TIS driver in git discards the timeout values returned
from the TPM. The check of the response packet needs to consider that
the return_code field is 0 on success and the size of the expected
packet is equivalent to the header size + u32 length indicator for the
TPM_GetCapability() result + 3 timeout indicators of type u32.
I am also adding a sysfs entry 'timeouts' showing the timeouts that are
being used.

This patch fixes an OOPS triggered when calling modprobe ipmi_si a
second time after the first modprobe returned without finding any ipmi
devices. This can happen if you reload the module after having the
first module load fail. The driver was not deregistering from PNP in
that case.
Peter Huewe originally reported this patch and supplied a fix, I have a
different patch based on Linus' suggestion that cleans things up a bit
more.

Some BIOSs (eg. the AMI BIOS on the Asus P4P800 motherboard) don't
initialise the GART address, and pcibios_assign_resources() can ignore it
because it can be marked as a host bridge (see
https://bugzilla.kernel.org/show_bug.cgi?id=24392#c5 for details). This
was handled correctly up to 2.6.35, but the pci_enable_device() cleanup in
2.6.36 96576a9e1a0cdb8 ("agp: intel-agp: do not use PCI resources before
pci_enable_device()") means that the kernel tries to enable the GART
before assigning it an address; in such cases the GART overlaps with other
device assignments and ends up being disabled.
This patch fixes https://bugzilla.kernel.org/show_bug.cgi?id=24392
Note that I imagine efficeon-agp.c probably has the same problem, but
I can't test that and I'd like to make sure this patch is suitable for
-stable (since 2.6.36 and 2.6.37 are affected).

This reverts commit f191f144079b0083c6fa7d01a4acbd7263fb5032.
The AMD 751 and 761 chipsets are used on the UP1000, UP1100, and UP1500
OEM motherboards, but they neglect to do anything to make AGP work.
According to Ivan Kokshaysky:
There is quite fundamental conflict between the Alpha architecture and
x86 AGP implementation - Alpha is entirely cache coherent by design,
while x86 AGP is not (I mean native AGP DMA transactions, not a PCI over
AGP). There are no such things as non-cacheable mappings or software
support for cache flushing/invalidation on Alpha, so x86 AGP code won't
work on Nautilus.
So there's no point in allowing this driver to be configured on Alpha.

The -rt patches change the console_semaphore to console_mutex. As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()
This commit makes things use more neutral function names which dont make
implications about the underlying lock.
The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()
This patch also paves the way to switching console_sem from a semaphore to
a mutex.

commit 3f0d3d016d89a5efb8b926d4707eb21fa13f3d27 adds a check for
PNP device id to the common tpm_tis_init() function, which in some
cases (force=1) will be called without the device being a member of
a pnp_dev. Oopsing and panics ensue.
Move the test up to before the call to tpm_tis_init(), since it
just modifies a global variable anyway.

If duration variable value is 0 at this point, it's because
chip->vendor.duration wasn't filled by tpm_get_timeouts() yet.
This patch sets then the lowest timeout just to give enough
time for tpm_get_timeouts() to further succeed.
This fix avoids long boot times in case another entity attempts
to send commands to the TPM when the TPM isn't accessible.

|
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

The newer drivers/gpio/cs5535-gpio.c replaces drivers/misc/cs5535_gpio.c.
The new driver has been in the tree for a little while, and has received
some testing; it's time to mark the old one as deprecated. I'm thinking
removal around 2.6.40 would be good, provided we're not missing critical
functionality in the newer driver.

KMSG_DUMP_PANIC
This series aims to develop logging facility for enterprise use.
It is important to save kernel messages reliably on enterprise system
because they are helpful for diagnosing system.
This series add kmsg_dump() to the paths loosing kernel messages. The use
case is the following.
[Use case of reboot/poweroff/halt/emergency_restart]
My company has often experienced the followings in our support service.
- Customer's system suddenly reboots.
- Customers ask us to investigate the reason of the reboot.
We recognize the fact itself because boot messages remain in
/var/log/messages. However, we can't investigate the reason why the
system rebooted, because the last messages don't remain. And off course
we can't explain the reason.
We can solve above problem with this patch as follows.
Case1: reboot with command
- We can see "Restarting system with command:" or ""Restarting system.".
Case2: halt with command
- We can see "System halted.".
Case3: poweroff with command
- We can see " Power down.".
Case4: emergency_restart with sysrq.
- We can see "Sysrq:" outputted in __handle_sysrq().
Case5: emergency_restart with softdog.
- We can see "Initiating system reboot" in watchdog_fire().
So, we can distinguish the reason of reboot, poweroff, halt and emergency_restart.
If customer executed reboot command, you may think the customer should
know the fact. However, they often claim they don't execute the command
when they rebooted system by mistake.
No message remains on the current Linux kernel, so we can't show the proof
to the customer. This patch improves this situation.
This patch:
Alters mtdoops and ramoops to perform their actions only for
KMSG_DUMP_PANIC, KMSG_DUMP_OOPS and KMSG_DUMP_KEXEC because they would
like to log crashes only.

Previous to the last GTT rework we always rewrote the GTT then unmapped the
object, somehow this got reversed in the rework in 2.6.37-rc5 timeframe.
This fix needs to go to stable in an alternate form since the code changed.
This fixes DMAR reports on my Ironlake HP2540p.

This code was setting up the status page before setting the DMAR-is-on-bit,
so we were getting DMAR errors on the status page. Reverse the two bits
of init code to the correct result.

Flush the chipset write buffers before and after adjusting the GTT base
register, just in case. We only modify this value upon initialisation
(boot and resume) so there should be no outstanding writes, however
there are always those persistent PGTBL_ER that keep getting reported
upon resume.
