The ACPI IPMI code doesn't seem to work on many real-world devices. Part of
that is because many shipping systems have a _CID of PNP0C01 or PNP0C02 and
the PNP core never lets the IPMI driver bind, but it's also a problem if
it's being used for AC adapter state (since they're typically built in)
Some IPMI callbacks may want to know how many IPMI devices were registered
or perform some specific action after probing has been completed. Add a
new callback to handle that.

Drivers may make calls that require the ACPI IPMI driver to have been
initialised already, so make sure that it appears earlier in the build

The ACPI spec makes it clear that IPMI operation regions should be declared
inside the scope of an IPMI device. Based on the existence of systems for
which this is untrue, it seems likely that alternative implementations exist
that perform some kind of fallback for regions outside the scope of an
IPMI must be initialised before ACPI in order to ensure that any IPMI
services are available before ACPI driver initialisation attempts to use
any IPMI operation regions.

As the function calls pcistub_device_get() before returning non-NULL,
its callers need to take care of calling pcistub_device_put() on
(mostly, but not exclusively) error paths.
Otoh, the function already guarantees that the 'dev' member is non-NULL
upon successful return, so callers do not need

Check the waitqueue task list to be non empty before entering the critical

Hi Andrew,
Today's linux-next merge of the akpm tree got a conflict in
include/linux/audit.h between commit e1760bd5ffae ("userns: Convert the
audit loginuid to be a kuid") from the userns tree and commit "audit.h:
replace defines with C stubs" from the akpm tree.
I fixed it up (see below) and
Hello,
It would be great if you could keep the correct authorship of the patch by

There are f.e. meminfo files in the per node directories in sysfs. It would

Hi,
I noticed the following:
In linux-mmotm and parisc-2.6.git trees,
arch/parisc/include/asm/compat_signal.h file is just:
/* Use generic */
#include
which isn't correct since asm-generic/compat_signal.h doesn't exist.
Nobody noticed this because arch/parisc/include/asm/compat_signal.h

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

I see. fileid seems to be stat.ino on nfsd4. inode->i_ino is actually
just a hash key of inode hash (exception is only in audit, iirc).
So, what happens if we set "stat->ino = i_pos" on

Hi Al,
Today's linux-next merge of the signal tree got a conflict in
arch/arm/include/asm/thread_info.h between commit 1f66e06fb641 ("ARM:
7524/1: support syscall tracing") from the arm tree and commit
