While writing to an event device allows to set repeat rate for an
individual input device there is no way to retrieve current settings
so we need to ressurect EVIOCGREP. Also ressurect EVIOCSREP so we

In case of an instruction processing damage (IPD) machine check in kernel mode
the resulting action is always to stop the kernel. This is not necessarily
the best solution since a retry of the failing instruction might succeed. Add

With CONFIG_SLAB_DEBUG=y networking over qeth doesn't work. The problem is
that the qib structure embedded in the qeth_irq structure needs an alignment
of 256 but kmalloc only guarantees an alignment of 8. When using SLAB
debugging the alignment of qeth_irq is not sufficient for the embedded qib
structure which causes all users of qdio (qeth and zfcp) to stop working.
Allocate qeth_irq structure with __get_free_page. That wastes a small amount
of memory (~2500 bytes) per online adapter.

The dasd state machine is not designed to enable an unformatted device, since

dasd_enable_device() which never returns if the device is in this special
state. Return -EPERM in dasd_increase_state for unformatted devices to make
dasd_enable_device terminate. Note: To get such an unformatted device online
it has to be re-analyzed. This means that the device needs to be disabled

The timeout and duration values used in the tpm driver are not exposed to
userspace. This patch converts the storage units to jiffies with
msecs_to_jiffies. They were always being used in jiffies so this
simplifies things removing the need for calculation all over the place.
The change necessitated a type change in the tpm_chip struct to hold
jiffies.

Many of the sysfs files were calling the TPM_GetCapability command with array.
Since for 1.2 more sysfs files of this type are coming I am generalizing the
array so there can be one array and the unique parts can be filled in just
before the command is called.
This updated version of the patch breaks the multi-value sysfs file into
separate files pointed out by Greg. It also addresses the code redundancy and
ugliness in the tpm_show_* functions pointed out on another patch by Dave
Hansen.

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.

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.

the only way for a user to enable it is via NET_RADIO. Some users need
to do that for out-of-tree drivers. Therefore it should be mentionned
in the title of the option.
Rationale2 : the option just below is called "Wireless

There are places in the kernel where we look up files in fd tables and
access the file structure without holding refereces to the file. So, we
need special care to avoid the race between looking up files in the fd
table and tearing down of the file in another CPU. Otherwise, one might
see a NULL f_dentry or such torn down version of the file. This patch
fixes those special places where such a race may happen.

This patch removes the EXPORT_SYMBOL_GPL of the static function cpufreq_parse_governor().
Signed-off-by: Adrian Bunk <bunk@stusta.de>
Signed-off-by: Dave Jones <davej@redhat.com>
The previous patch had bugs (locking and refcount).
This one could also be related to the latest DELL reports.
But they only slip into this if a user prog (e.g. powersave daemon does when
AC got (un) plugged due to a scheme change) echos something to
/sys/../cpufreq/scaling_governor
while the frequencies got limited by BIOS.
This one works:
Subject: Max freq stucks at low freq if reduced by _PPC and sysfs gov access
The problem is reproducable by(if machine is limiting freqs via BIOS):
- Unplugging AC -> max freq gets limited
- echo ${governor} >/sys/.../cpufreq/scaling_governor (policy->user_data.max
gets overridden with policy->max and will never come up again.)
This patch exchanged the cpufreq_set_policy call to __cpufreq_set_policy and
duplicated it's functionality but did not override user_data.max.
The same happens with overridding min/max values. If freqs are limited and
you override the min freq value, the max freq global value will also get
stuck to the limited freq, even if BIOS allows all freqs again.
Last scenario does only happen if BIOS does not reduce the frequency
to the lowest value (should never happen, just for correctness...)

[PATCH] i2c-parport: Make type parameter mandatory
This patch forces the user to specify what type of adapter is present when

init simply fails - instead of assuming adapter type 0.
This alleviates the sometimes lengthy boot time delays which can be caused
by accidentally building one of these into a kernel along with several i2c
slave drivers that have lengthy probe routines (e.g. hwmon drivers).
Kconfig and documentation updated accordingly.

[PATCH] DMI: move dmi_scan.c from arch/i386 to drivers/firmware/
dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64.
Currently all three arches compile it from arch/i386, which means that ia64

This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing
trailing whitespace) and the associated Makefile changes. All three
architectures already set CONFIG_DMI in their top-level Kconfig files.

The init function for the RPA PCI Hotplug driver returns -ENODEV in the
case that no hotplug-capable slots are detected in the system. This is
bad, since hot-capable slots can be added after boot to a purely virtual
POWER partition. This is also bad because DLPAR I/O operations depend
on the rpaphp module.
Change the rpaphp init module to return success for the case of
partitions that own no hotplug-capable slots at boot. Such slots can be
dynamically added after boot.

The manual driver <-> device binding attribute in sysfs doesn't return
the correct value on failure or success of driver_probe_device.
driver_probe_device returns 1 on success (the driver accepted the
device) or 0 on probe failure (when the driver didn't accept the
device but no real error occured). However, the attribute can't just
return 0 or 1, it must return the number of bytes consumed from buf
or an error value. Returning 0 indicates to userspace that nothing
was written (even though the kernel has tried to do the bind/probe and
failed). Returning 1 indicates that only one character was accepted in
which case userspace will re-try the write with a partial string.
A more correct version of driver_bind would return count (to indicate
the entire string was consumed) when driver_probe_device returns 1
and -ENODEV when driver_probe_device returns 0. This patch makes that
change.

It works like this:
Open the file
Read all the contents.
Call poll requesting POLLERR or POLLPRI (so select/exceptfds works)
When poll returns,
close the file and go to top of loop.
or lseek to start of file and go back to the 'read'.
Events are signaled by an object manager calling
sysfs_notify(kobj, dir, attr);
If the dir is non-NULL, it is used to find a subdirectory which
contains the attribute (presumably created by sysfs_create_group).
This has a cost of one int per attribute, one wait_queuehead per kobject,
one int per open file.
The name "sysfs_notify" may be confused with the inotify
functionality. Maybe it would be nice to support inotify for sysfs
attributes as well?
This patch also uses sysfs_notify to allow /sys/block/md*/md/sync_action
