Traversal of the ACPI device tree was not done right. It should lookup
PPI only under the ACPI device that it is associated. Otherwise, it could
match to a wrong PPI interface if there are two TPM devices in the device
tree.

This patch set fixes two race conditions in the TPM subsystem:
* Two-phase initialization for struct tpm_chip so that device can
initialize fully initialize before exposing itself to the user
space. Also, in future TPM2 devices must be flagged before they
can be registered.
* Machines where
Merged transmit_cmd() functions in tpm-interface.c and tpm-sysfs.c.
Added "tpm_" prefix for consistency sake. Changed cmd parameter as
opaque. This enables to use separate command structures for TPM1
and TPM2 commands in future. Loose coupling works fine here.

Most iomux controllers allow a configuration per pin. These currently
have no common device tree binding. There are many different SoC
specific bindings for this class of iomux controllers. Some controllers
artificially group pins together where in hardware no groups exist (for

There have been several times where I have had to rebuild a kernel to

Hello,
The Project is about the exportation of 100,000 barrels of Light Crude Oil
daily out from Iraq to Turkey through my client's company in Iraq at the rate
of $85.00 a barrel. This amount to $8,500,000.00 daily. I ask for your support

Several systems are showing the following stack trace:
WARNING: CPU: 0 PID: 2352 at lib/dma-debug.c:1140 check_unmap+0x4ee/0x9e0()
ioatdma :00:04.0: DMA-API: device driver failed to check map error[device

When the error code is -EPROBE_DEFER, this will already be reported
so don't emit an error message in that case.

Remove stop_machine from module unloading by adding new reference
counting algorithm.
This atomic refcounter works like a semaphore, it can get (be
incremented) only when the counter is not 0. When loading a module,
kmodule subsystem sets the counter MODULE_REF_BASE (= 1). And when
unloading the m

It disables interrupts so that the chance of the oops getting out is
maximised, it locks down some of the other bits to try and stop
interleaved oopses
"ret" is a signed int, so use "%d" in format strings instead of "%u".
This prevents cryptic codes in error messages like this:
sdhci-arasan e0101000.sdhci: platform register failed (4294966779)

Replace module_ref per-cpu complex reference counter with
an atomic_t simple refcnt. This is for code simplification.

Actually since module_bug_list should be used in BUG context,
we may not need this. But for someone who want to use this
from normal context, this makes module_bug_list an RCU list.

Unlink module from module list with RCU synchronizing instead
of using stop_machine(). Since module list is already protected
by rcu, we don't need stop_machine() anymore.

Wait for RCU synchronizing on failure path of module loading
before releasing struct module, because the memory of mod->list
can still be accessed by list walkers (e.g. kallsyms).

Hi,
Here is the second version of removing stop_machine() from
module unloading patchset.
Currently, each module unloading calls stop_machine()s 2 times.
One is for safely removing module from lists and one is to
check the reference counter. However, both are not necessary
for those purposes (req

Sounds reasonable, but are you sure, that we can just drop skb->pfmemalloc flag
in napi_reuse_skb()?

This removes the ipmi_devintf to be a module, but it will automatically
be compiled into ipmi_msghandler module if IPMI_HANDLER is set.
This will allow userspace IPMI support via autoloading.
There already was a kind of autoloading mechanism (gets deleted
with this patch):
-MODULE_ALIAS("platform:
This removes the ipmi_devintf to be a module, but it will automatically
be compiled in if ipmi_msghandler is set.
This will remove the overhead of an additional module (unneeded memory and
sysfs files and additional autoloading of the userspace interface
(which was broken) is not needed anymore.
There should be no need to specify the major number of /dev/ipmiX via module
parameter.
Major number is now always allocated dynamically.
