442a4fffff random: update interface comments to reflect reality
At present, the comment header in random.c makes no mention of
add_disk_randomness, and instead, suggests that disk activity adds to the
random pool by way of add_interrupt_randomness, which appears to not have
been the case since sometime prior to the existence of git, and even prior
to bitkeeper. Didn't look any further back. At least, as far as I can
tell, there are no storage drivers setting IRQF_SAMPLE_RANDOM, which is a
requirement for add_interrupt_randomness to trigger, so the only way for a
disk to contribute entropy is by way of add_disk_randomness. Update
comments accordingly, complete with special mention about solid state
drives being a crappy source of entropy (see e2e1a148bc for reference).

This reverts commit 9b29050f8f75916f974a2d231ae5d3cd59792296.

It has caused hibernate regressions, for example Juri Sladby's report:

  "I'm unable to hibernate 2.6.37.1 unless I rmmod tpm_tis:
   [10974.074587] Suspending console(s) (use no_console_suspend to debug)

   [10974.103095] PM: Device 00:0c failed to freeze: error -62"

and Rafael points out that some of the new conditionals in that commit
seem to make no sense.  This commit needs more work and testing, let's
revert it for now.

d5bb2923cf drivers/char/pcmcia/ipwireless/main.c: Convert release_resource to 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:

expression x,E;
@@

*x = request_region(...)

We don't actually need this and it causes problems for internal use of

That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.

c652759b6a hwrng: omap - Convert release_resource to release_region/release_mem_region
Request_region should be used with release_region, not release_resource.

The local variable mem, storing the result of request_mem_region, is
dropped and instead the pointer res is stored in the drvdata field of the
platform device.  This information is retrieved in omap_rng_remove to
release the region.  The drvdata field is not used elsewhere.

9b29050f8f tpm_tis: Use timeouts returned from TPM
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.

d2478521af char/ipmi: fix OOPS caused by pnp_unregister_driver on unregistered driver
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.

a70b95c017 agp: ensure GART has an address before enabling it
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).

cecd1455bc Revert "agp: AMD AGP is used on UP1100 & UP1500 alpha boxen"
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.

ac751efa6a console: rename acquire/release_console_sem() to console_lock/unlock()
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.

bee4a186c1 drm/i915,agp/intel: Do not clear stolen entries
We can only utilize the stolen portion of the GTT if we are in sole
charge of the hardware. This is only true if using GEM and KMS,
otherwise VESA continues to access stolen memory.

e5cce6c13c tpm: fix panic caused by "tpm: Autodetect itpm devices"
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.

c4ff4b829e TPM: Long default timeout fix
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.

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
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.

ab4382d274 tty: move drivers/serial/ to drivers/tty/serial/
The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.

This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.

was also moved, as it required the hvc_console.h file to be able to be
